In 1970, Optronic Laboratories was established as an optical radiation instrumentation, standards, and calibration laboratory. Forming the nucleus of the company were two former NIST (National Institute of Standards and Technology) physicists, who had individually made significant contributions to the fields of spectroradiometry and electro-optical technology. The company was established to eliminate a void that existed in the area of optical radiation standards, calibration services, and measurement instrumentation for industry, government/military, and academia. In 1995, the company was acquired by Gooch & Housego but continued to do business under the Optronic Laboratories name. In 2006, ChromoDynamics, manufacturer of hyperspectral imaging systems in New Jersey, was also acquired. As of January 2010, both companies were merged to form the Life Sciences & Instrumentation division of Gooch & Housego. Together with the company's Materials and Components enterprises, the division helps to broaden the well-known and trusted brand's offerings and leverage Gooch & Housego's extensive worldwide engineering, operations, sales, distribution, and support channels to enhance our response to our clients' specific needs.

OL 770-LED TEST & MEASUREMENT SYSTEM

1

The OL 770-LED is a high speed, CCD-based spectroradiometer system optimized to perform all critical measurements of light emitting diodes (LEDs), LED clusters, LED chips, and more. The OL 770-LED was designed for customers who require fast measurement results but not at the expense of quality, color consistency, or precision. The OL 770-LED is accurate enough to characterize LED components for R&D purposes, but economical, lightweight, and portable enough for performing rapid QC checks on the production floor. The OL 770-LED is fully compliant with CIE Publication 127. The OL 770-LED’s control electronics, internal spectrograph, and detector are housed in one rugged, portable enclosure. Its lightweight and small footprint design, relative to larger scanning spectroradiometers, makes it an ideal instrument for use in production environments, especially where portability is needed. The instrument is equipped with both RS-232 and Universal Serial Bus (USB) interfaces, thus a plug-in card for the PC host is not required. The USB interface provides for extremely fast measurements and allows laptops to be utilized. The OL 770-LED sets up quickly with a simple flip of the on/off switch. The fiber optic plugs into the entrance port on the front of the unit, enabling the user to place the test module in a convenient location. The unique internal spectrograph is based on an aberration corrected, concave, flat field diffraction grating. The precision optics of the spectrograph delivers low stray light performance, high spectral resolution, and excellent wavelength accuracy. The standard grating operates over the 380 to 780 nm wavelength range. Other wavelength ranges are available for the ultraviolet and near infrared regions. Optical input to the spectrograph is made via a fiber optic cable. An interchangeable slit (100 microns standard) is provided in the entrance port on the front panel of the OL 770-LED. Other slit sizes for varying the optical bandwidth are available.

OL 700-70 Integrating Sphere Reflectance Attachment _____________________

The OL 700-70 is used with the OL Series 770 to measure the diffuse reflectance of materials over the UV-VIS-NIR wavelength region. The attachment utilizes fiber optic coupled input and output ports, and a 6" diameter integrating sphere. It is mounted in a convenient, rugged stand for tabletop or laboratory benchtop use, eliminating the need for mounting rods or fixtures. Sample measurement spot size is 5 mm, and due to the unique sample holder design, there is no limit to the actual size of the sample. Although the OL 700-70 was designed specifically for use with the OL 770, it can also be used with other spectroradiometers equipped with a fiber optic input.

• Ultra-fast measurement of samples The entire spectrum, plus chromaticity and other essential optical parameters, is measured in a fraction of a second.

• Complete flexibility Light to and from the sample is carried by flexible fiber optics, so the OL 700-70 can be easily positioned relative to your samples.

• Samples can be horizontal or vertical The OL 700-70 is designed to operate both horizontally and vertically, so it can match the orientation of your samples.

• Any size samples Remove the sample holder and place the sample against the flat surface. The sample can be as big as you like. You can even place the OL 700-70 port-down onto a sample, e.g. a table, and measure its reflectance.

• Accurate results All the features needed for the most accurate measurements are included. You get the benefits of sample self-absorption compensation, low stray light, double beam geometry, ultra-stable stable light source, and near-ideal Lambertian sampling – all critical for accurate measurements.

• Specular components included or excluded Make measurements of all types of samples, with diffuse only or diffuse + specular (mirror-like) results.

• Easy-to-use software The software guides you through making measurements, data storage, and reports with just a simple mouse-click.

• Microsoft Word and Excel compatible The system is designed to work with Microsoft

Word and Excel, allowing infinite flexibility.

An accurate, double-beam design is achieved with a manually controlled, optical beam switch. The double-beam design enables the user to use the significantly more accurate "comparison method” of measuring diffuse reflectance. This method compensates for changes in the spectral efficiency of the integrating sphere due to self-absorption and reflectance properties of the measurement sample when placed on the measurement port. The angle of incidence from the input port to the measurement port is 10°, and the reflected specular component may be included or excluded due to a removable light trap. When the specular component is to be included in the measurement, a PTFE coated plug is installed in place of the light trap. This optical design also enables the user to measure specular reflectance at a fixed angle of incidence of 10°. A calibrated standard of diffuse reflectance and a built-in lamp used for illumination of the sample are provided for calibration and measurements. Control of the illumination source is imbedded in the application software, and software prompts fully guide the user through the calibration and measurements procedure.

OL 700-71 6” Integrating Sphere - Enables the user to make diffuse spectral reflectance measurements of various materials over all or part of the wavelength range from 250 nm to 1100 nm. Sophisticated optical design allows for accurate measurements to be made of specular (mirror) samples as well as diffuse samples with the specular component included or excluded. Sample measurement spot size is 3 mm, and due to the unique sample holder design, there is no limit to the actual size of the sample. An accurate, double-beam design is achieved with a manually controlled, optical beam switch. The double-beam design enables the user to use the significantly more accurate "Comparison Method” of measuring diffuse reflectance. This method compensates for changes in the spectral efficiency of the integrating sphere due to self-absorption and reflectance properties of the measurement

sample when placed on the measurement port.

The angle of incidence from the input port to the measurement port is 10°, and the reflected specular component may be included or excluded due to a removable light trap. When the specular component is to be included in the measurement, a PTFE coated plug is installed in place of the light trap. This optical design also enables the user to measure specular reflectance at a fixed angle of incidence of 10°. Control of the OL 700-22 pulsed Xenon source is imbedded in the application software, and software prompts fully guide the user through the calibration and measurements procedure.

Uniquely, the OL 700-71 also provided the capability to measure transmittance of samples, whether regular or diffuse, using the same accurate double beam techniques as the diffuse reflectance. Because both transmittance and reflectance of the same part of the sample is measured without moving the sample, the amount of light absorbed inside the sample

can be determined with high precision. The software provides transmittance, reflectance, and absorptance, as well as derived quantities such as optical density, Kubelks-Monk values, and internal absorbance. OL 700-73 Solid Transmittance - Utilized for performing spectral transmittance measurements of samples in solid form. Has a slide-in sample holder that accommodates both 1-inch by 1-inch, and 2-inch by 2-inch square samples, as well as 1-inch diameter and 2-inch diameter round samples. Samples can be up to ½-inch in thickness

OL 700-86VP Vacuum Pump Assembly _________________________________ The OL 700-86VP Vacuum Pump Assembly is designed to work in conjunction with the OL Series 700-86 Vacuum Chuck LED Holder to firmly secure surface-mount style LEDs onto the LED Holder. The pump assembly is a complete unit consisting of a diaphragm pump, an adjustable pressure valve, a vacuum gauge, a vacuum line shut-off valve, and a quick-release hose connector all housed in a portable fan cooled enclosure. A 6-foot (1.8 meter) extension hose with the appropriate adapters is provided to help in placing the LED Holder in a remote location. The vacuum pump contains a convoluted diaphragm in a unique pump cavity designed to provide extended life by minimizing

stress, wear and heat buildup. The pump motor is totally enclosed, thermally protected and utilizes sealed ball bearings for long life. The adjustable pressure needle valve is used to select the proper vacuum pressure required to hold the LED being tested. Once set, the adjustment knob can be locked into place by using the locking ring. The vacuum gauge reading can be varied by using the adjustable pressure needle valve, and shows the amount of vacuum pressure applied to the LED Holder. It displays a vacuum value in inch-mercury (in Hg) units. The shut-off valve is a quarter-turn ball valve and is used to remove the vacuum from the LED Holder without having to readjust the needle valve or turn the pump off.

OL 700-88TC Liquid Cooled Temperature Controller ______________________

The advent of high brightness LEDs and other solid-state lighting sources has created challenges for thermal management for device developers and lighting designers who create or implement such devices. In response to this need, Gooch & Housego has developed the OL Series 700-88 Temperature Controlled LED Holders, which utilize recirculating liquid to dissipate the heat from the more powerful new LED devices. The holders are used with the OL 700-88TC Liquid Cooled Temperature Controller, which maintains device temperature by recirculating chilled or warmed water through the holders. Changes can be made manually using the front panel display on the controller, which shows the set point temperature and the temperature of the portion of the holder in contact with the device under test (DUT). With the OL 770 Application Software, the temperature set point may be programmed and the device temperature can be displayed as part of the value tree. The data can then be easily exported to Microsoft Excel

® and Word

® for analysis or report generation. The OL 700-88 holders are compatible with the OL IS-670 and OL

IS-1800 Integrating Spheres, and OL 15AB LED Receptor. Use with the OL 700-30 Goniometer is not recommended.

(1.5 kg) OL 770-420 Software Development Kit (SDK) ____________________________ The OL 770-420 Software Development Kit (SDK) for the OL 770 and OL 771 spectroradiometers enables programmers to develop their own custom applications or integrate the OL 770/ 771 application into existing automated test and measurement systems. It is recommended that the user become familiar with the OL 770/ 771

Windows Application Software before developing their own application.

The SDK for the OL 770/ 771 is comprised of:

� OL770 Application Software CD ROM with ActiveX control and license file � Automation Server Test Panel with help file, source code and license file

� LabVIEW Panel Application with help file and source code

� Delphi Application Panel with source code

� Visual Basic 6.0 Panel Application with source code

� Visual C# Panel Application and source code

The ActiveX Control

This control allows the user to have low-level control of the instrument. Absolute measurement results are not included. This control is actually used by the OL 770/ 771 application to communicate with the OL 770/ 771 spectroradiometer. (An

ActiveX control is not a stand-alone program but relies on a container application to activate it.)


16

The ActiveX Automation Server

The automation server is actually part of the OL 770/ 771 application. Functionality is “exposed” to the programmer, allowing function calls that perform very high level capabilities. The user can acquire absolute measurements and retrieve calculated values, such as chromaticity, correlated color temperature, etc. Since the server is actually the OL 770/ 771 application, the user can load and save CFG files with customer configurations. In most cases, users will want to use this method of programming.

Most programming environments such as Visual C++, Visual Basic, Excel VBA, or LabVIEW can use any of the ActiveX technologies.

LabVIEW Panel Application

The LabVIEW panel application connects to the instrument via serial or USB ports. This program provides control of the instrument and is supplied as a sample program. It employs the ActiveX Automation Server. Source code (VI files) used to develop this application is also included. The VIs function as LabVIEW instrument drivers for customers who own LabVIEW and wish to develop their custom applications in this development environment.

Delphi Panel Application

This is a program that serves as an instrument controller, as an example ActiveX container, and also as a diagnostic tool. It employs the ActiveX Automation Server. The provided source code is written in Delphi and was developed in

Borland Delphi 6.0.

Visual Basic Panel Application This is a program that serves as an instrument controller, as an example ActiveX container, and also as a diagnostic tool. It employs the ActiveX Automation Server. The provided source code is written in Visual Basic and was developed in Visual Basic 6.0. Visual C# Panel Application This is a program that serves as an instrument controller, as an example ActiveX container, and also as a diagnostic tool. It employs the ActiveX Automation Server.

OL IS-670-LED Integrating Sphere ______________________________________ The OL IS-670-LED Integrating Sphere is designed specifically for use with the OL 770-LED High-speed LED Test and Measurement System to provide accurate measurements of many properties of light emitting diodes, and permits the user to make color measurements in accordance to recommendations by NIST and CIE Publication 127.

The OL IS-670-LED provides an accurate means of measuring the total spectral luminous flux and total radiant flux of

“forward-looking” LEDs. The OL 770-LED Windows® software provides instant measurement data reduction for such

quantities as:

• Total Radiant Flux (watts)

• Total Luminous Flux (lumens)

• Total Spectral Flux (watts/nm)

• Dominant Wavelength

• Peak Wavelength

• Half-bandwidth

• Color Purity

• Correlated Color Temperature

• Color Rendering Indices

• Chromaticity Coordinates

NOTE: Due to some incompatibility with LabVIEW 6.0, the OL 770 Software Development Kit (SDK) is not guaranteed to work in the LabVIEW 6.0

environment. However, the SDK has been tested on LabVIEW 5.0 and LabVIEW 7.0.


18

The OL 770-LED/IS-670-LED combination incorporates features such as an internal reference/auxiliary lamp and a nearly perfect cosine response to eliminate major sources of error. The OL IS-670-LED consists of a 6-inch diameter, PTFE coated, high reflectance integrating sphere. It is mounted in a convenient, rugged stand for tabletop or laboratory benchtop use, eliminating the need for mounting rods or fixtures. The sphere has a 90° entrance port to exit port configuration and includes a SMA connector for connection of the auxiliary lamp incorporated into .the OL 770-LED via an optical fiber.

The OL IS-670-LED yields spectral reflectance properties > 99% in the 300 nm to 1700 nm wavelength range. A coated internal baffle in front of the exit port prevents non-integrated light from exiting the sphere. The exit port of the sphere is coupled to the OL 770-LED via a fiber optic cable.

A wide range of off the shelf LED holders is available, as well as custom LED holders for specific device configurations.

A unique feature of the OL 770-LED/IS-670-LED combination is that it includes an internal reference/auxiliary lamp not

found in systems available from other manufacturers. This built-in reference/auxiliary lamp is used to calibrate the integrating sphere and compensate for changes in the spectral efficiency of the integrating sphere due to self-absorption and reflectance properties of LEDs. This provides for accurate on-site calibrations and is so easy to use that inexperienced personnel can perform them. It sharply contrasts with competitor’s systems that need to be shipped back for calibration since:

OL 750 Spectroradiometric Measurement System _________________________

The OL Series 750 Automated Spectroradiometric Measurement system is controlled by the OL 750-C controller, which houses all the electronics, data acquisition, monochromator, and accessory control. The all-in-one controller is connected to your PC via RS-232 interface as standard, or IEEE-488 as an option. The heart of the system is your choice of a single (OL 750-M-S) or double (OL 750-M-D) high-efficiency (f/4) scanning monochromator. Each monochromator is precisely fabricated and assembled in our plant to exacting specifications. Each is configured with a computer-controlled, tri-grating mount as standard. Up to three (3) large 68 x 68 mm gratings are employed for superior optical performance from 200 nm through 30 µm, covering the entire ultraviolet-visible-infrared spectrum. The system is entirely computer-controlled through its Windows

®- based application software. No manual operation of

any controls is required. Every function from grating turret and filter wheel rotation to detector set-up, data reduction, and calibration routines is controlled via the software and your PC.

Source Analysis _______________________________________________________________________ This covers a broad range of spectroradiometric measurements for all sorts of light sources. Equipped with the appropriate input optics, you will achieve the most precise measurements for light sources, such as:

Arc lamps Blackbody Sources Flash lamps Fluorescent lamps Growth chambers Laser Diodes LEDs Low light level sources Pulsed sources Star simulators Solar simulators Solar radiation

Sphere sources Tungsten lamps


32

Input optics include:

� Integrating spheres for measuring spectral irradiance or power � Reflex telescopes when you need to measure spectral radiance or radiant intensity at large distances � Reflex microscopes for measuring the spectral radiance of very small light sources � Mirror imaging optics for spectral radiance measurements from 200 nm to 30 µm

Transmittance _________________________________________________________________________ Coupled with a UV-VIS-IR source, collimator, and integrating sphere, the OL Series 750 can measure both the normal and diffuse spectral transmittance of various materials, such as lenses and filters. Transmittance can be measured in terms of percent transmittance, optical density, absorbance, or photometric transmittance.

Specular Reflectance ___________________________________________________________________ The OL Series 750 can be configured with the OL 750-75MA Goniospectroreflectance Attachment to measure the specular reflectance of polished materials or mirrors as a function of both wavelength and angle of incidence. Achieving precise and accurate measurements are critical in applications such as:

Lens coating Automotive windshields Headlamps housings & mirrors Paint-finished surfaces & shellacs Windows and portals Building materials

Computer monitor and television screen surfaces

Specular Reflectance ___________________________________________________________________ When you need to quantify the reflectance of light scattering in all directions from a surface, there is no better system available than the OL Series 750 configured with an OL 740-70 Integrating Sphere Diffuse Reflectance Attachment. The OL 740-70 uses all mirror optics in a true double beam optical design. A light trap inserted at the specular position of the sphere wall provides for diffuse reflectance measurements with the specular component removed. Diffuse spectral reflectance measurements can be made including or excluding the specular component on material such as

Powder Paint Cosmetics Plastics Glasses Food

Detector Response _____________________________________________________________________ Adding source imaging optics mounted at the entrance slit of the monochromator, exit optics that produce a uniform, collimated monochromatic beam at the exit slit and a standard calibrated reference detector, converts your OL Series 750 into a measurement system for determining detector response. Types of detectors that can be analyzed include:

Photomultiplier Silicon Germanium InGaAs Lead Sulfide Lead Selenide InSb HgCdTe Pyroelectric CCD Cameras Radiometers

Photometers

SOFTWARE ___________________________________________________________________________ The OL Series 750 application software is a highly intuitive Windows

A typical 3.0 mm diameter circular monochromator exit slit will form a 4.5 mm spot at the detector. Dual concentric rotary tables for the sample holder and detector mount are driven by independently-controlled precision worm gears. Samples are held in an adjustable mount at the center of a 6” rotary table. The standard sample holder can accommodate a 2” to 4” circular sample, or 2” x 2” or 4” x 6” rectangular samples. Sample thickness can range from 1/16” to ½”. Custom sample holders and beam polarizers are also available. An important feature of the OL 750-75MA is the “self-calibrating” capability. Accurate measurements of specular reflectance can be made without the use of a standard (calibrated mirror). The detector view angle may be positioned at the 0° incident angle position for a 100% reading. Specular reflectance measurements can the be made on various samples from 10° to 60° with an angular accuracy of ± 1°.

OL 750-423 Pulsed Integration Software ________________________________

The OL Series 750 can be configured to measure the spectral energy output of pulsed sources. The following should

be noted when configuring the OL Series 750 for pulsed source measurements: 1. The OL Series 750 must be equipped with both the OL 750-423 Source Spectral Analysis and OL 750-423P Pulsed

Integration Software. 2. The OL Series 750 must be equipped with both the OL 750-SDS-210 DC Signal Detection System and OL 750-

SDS-230 Pulse Integration Signal Detection System.

3. Only silicon, germanium, InGaAs, or PMT detectors can be used with the OL Series 750 for pulse integration

measurements. Thus, the wavelength range for pulse integration measurements is restricted to 200 to 1800 nm. 4. An OL 750-611 or OL 750-612 Detector Head Adapter is needed to interface the appropriate Detector Head to the

BNC on the rear panel of the OL 750C Controller. Non-TE cooled detectors (silicon, PMT) require the OL 750-611 Detector Head Adapter. TE cooled detectors (Ge, InGaAs) require the OL 750-640 TE Cooler for OL 750-HSD TE Cooled Detectors, and the OL 750-612 TE Cooled Detector Head Adapter. Note, a Detector Support Module is not needed for pulse integration measurements.

OL 750-423P Pulse Integration Software

The OL 750-423P enables the system to measure the spectral energy output of pulsed sources with the aid of the OL

750-SDS-230 Pulse Integration Signal Detection System. The 750-423P is similar in operation as the 750-423;

however, appropriate commands have been added at select locations in order to control the pulse integrator in the OL

750-C Controller.

In addition to the normal parameters such as: beginning wavelength; ending wavelength; and wavelength increment, the user is required to enter the amount of time in units of milliseconds that is necessary for the pulsed source to recharge after firing. The program will automatically wait this period of time between consecutive flashes. The OL 750-423P uses the same calibration factor data files as used with the 750-423; however, where the 750-423 uses amperes, the 750-423P uses coulombs. The OL 750-423P controls the following functions on the Pulse Integrator: � Source synchronization pulse width � Source synchronization mode (internal, external, or keyboard triggered) � The autozero circuit (nulls detector dark current)

OL 750-SDS-230 Pulse Integrator Signal Detection System The OL 750-SDS-230 features software controlled automatic and manual source synchronization modes. When operating in automatic synchronization mode, the source may be triggered by a TTL pulse provided by the OL 750-C Controller, or the pulse integrator may be triggered externally by the source to begin the pulse measurement sequence. When operating in manual mode, the user presses a key and the OL 750-C triggers the source and the pulse measurement sequence is initiated. High-isolation relays providing very low leakage currents are used. High or low dark current compensation may be selected for using detectors that exhibit low dark current levels such as silicon, or detectors that exhibit high dark current levels (PMTs).

Each high sensitivity detector module consists of two parts: the detector head and the detector support module. The detector head contains the detector element and thermoelectric or LN2 cooler (if applicable). The detector support module contains the high sensitivity preamplifier and detector bias electronics. An ultra low-noise connector is used to interface the detector head to the detector support module. By locating the preamplifier physically close to the detector, the optimum performance is realized. The acquisition, amplification, and mode of signal processing are designated as the Signal Detection System. The OL Series 750 can be obtained with one or more of the following Signal Detection Systems: DC Amplification (OL 750-SDS-210) ...................................................................................................................................... DC

AC Lock-In Amplification (OL 750-SDS-220) ......................................................................................................................... AC

Pulse Integration (OL 750-SDS-230) ....................................................................................................................................... PI

Accordingly, each High Sensitivity Detector is optimized for use with a specific Signal Detection System. This unique feature enables the user to optimize the overall system sensitivity for any application by coupling the Signal Detection System with the most appropriate High Sensitivity Detector.

A listing of the OL Series 750 High Sensitivity Detectors along with general specifications is given on following pages, as well as spectral response curves.

OL 730D Radiometer/ Photometer ______________________________________

• Characterize light sources and materials over all or part of the entire UV/VIS/IR region (200

nm to 30 µm)

• Measure true RMS intensities of AC, pulsed or modulated sources

• Measure total, peak, average, apparent intensities and time profiles of pulsed and navigation lights

• Eliminate noise from sources and detectors

• Attain the ultimate in sensitivity, down to and including counting individual photons

• Computer control for integration into existing measurement procedures or custom data analysis

The OL 730D is an extremely versatile radiometer utilizing state-of-the-art digital signal processing (DSP) technology. When used with a wide range of optional photodetectors and input optics, a multitude of high accuracy radiometric and photometric measurements can be made over all or part of the entire ultraviolet, visible and infrared spectrum. The OL 730D features several modes of operation. It can be operated as:

• a high sensitivity DC amplifier, typically used in photometric or radiometric measurements in the UV/VIS/NIR regions

• an AC lock-in amplifier, typically used for measurements in the IR (1.8 µm to 30 µm) and highly modulated source applications

• a photon counter for extremely low-light-level measurements.

Ultra high-speed data acquisition is another important feature of DSP technology. This means that the OL 730D can measure the output of pulsed or rapidly changing sources in addition to performing source profiling.


50

The OL 730D is a completely microprocessor-controlled, multi-functional radiometer/photometer, which can be programmed to read directly in any user specified radiometric or photometric optical quantity. The OL 730D is virtually ideal for all types of measurement and features high sensitivity, autoranging, auto-zeroing, highly accurate readout and range-to-range linearity, 4½ digit (6½ digit via computer) plus exponent display, user variable response time, an extremely large dynamic range and RS-232-Interface (IEEE-488 optional) for computer control. Multiple calibration factors for different detector/filter/input optic configurations can be stored in memory. Once the desired configuration and associated calibration factor is selected, the OL 730D will measure and read directly in the designated optical units.

OL 730D APPLICATIONS DC Radiometer/ Photometer Mode – The high accuracy and high conversion rate of the OL 730D electronics combined with DSP low-pass filtering enables the OL 730D to accurately measure the current generated by DC operated detectors. Thus, when configured with the appropriate detector/ filter/ input optics, the OL 730D operates as an extremely sensitive radiometer or photometer capable of measuring detector signals from 1 x 10-14 to 2 x 10-3 amperes. The actual photometric and radiometric sensitivities are, of course, dependant on the choice of detector, filter(s), and input optics. AC Radiometer/ Photometer Mode – When used in the AC Mode, the OL 730D is a complete dual-phase lock-in amplifier that uses DSP to perform the “synchronous rectification” that is central to the operation of all lock-in amplifiers. The digital techniques employed in the OL 730D significantly reduce errors such as non-linearity, offset and drift, harmonic distortion, and temperature effects that are inherent in classical analog lock-in amplifiers. However, the greatest benefit to the user is the performance enhancement at the lower signal levels. The OL 730D features a built-in, variable frequency optical chopper controller. The OL 730D-CH Programmable Variable Speed Optical Chopper is available as a stand-alone option.

OL 730D OPTIONS The basic OL 730D is furnished with DC and AC lock-in capabilities. The following features are available as options: OL 730D-PC Photon Counting Option – When used with the appropriate photon counting photodetector, the OL 730D-PC provides the ultimate sensitivity with excellent linearity from 1 to 1,000,000 counts per second. The OL 730D-HV High Voltage DC Power Supply – A programmable, high voltage DC power supply for use with photomultiplier detectors. DC voltage can be varied from ) to -1500 VDC with ultra low ripple and drift. OL 730D0CH Optical Chopper – The OL 730D-CH consists of integrated control electronics and chopper enclosure along with a control cable. A precision DC motor assembly with an integrated optical encoder is mounted in a machined, metal enclosure that can easily be mounted to an optical bench. The standard 4-slot blade provides chopper frequencies from 10 to 350 Hz. An optional 18-slot blade extends the frequency range from 180 to 1200 Hz. OL 730D-IEEE488 Communications Interface – An IEEE-488 Interface supplements the standard RS232. Photon Counting Radiometer/ Photometer Mode – By utilizing and enhancing some rarely used inherent features of the DSP chip, the OL 730D can be used with photon counting photomultipliers to achieve the ultimate photometric or radiometric sensitivity. The photon counting option provides excellent sensitivity and linearity in the count range of 1 to 1,000,000 counts per second.

OL 490 Agile Light Source _____________________________________________ Capable of producing emissions at a single wavelength or broad spectrum. Steady state or varying with time. Gooch & Housego’s OL 490 Agile Light Source utilizes Texas Instruments’ innovative Digital Light Processor technology (DLP

®) to offer a programmable and variable high intensity and high resolution

spectral output. The OL 490 is the next generation of precision spectral light sources and delivers an unprecedented level of flexibility and speed to a wide range of scientific and technical applications, including:

Chemometrics and Hazardous Materials – The agile light source enables generation of synthetic spectra, which can be used for truthing of hazardous materials (HAZMAT) sensing technology. Although a variety of conventional and novel sensing technologies are now available for detecting pathogenic agents, few methods exist for testing their effectiveness. The OL 490 can be programmed to synthesize spectra rendering development and calibration processes routine and eliminate the need to handle such substances directly.

Figure 3 – Opto-Mechanical Layout of the OL 731 USB Smart Detector (shown without filters)

SPECTRAL IMAGING & SYNTHESIS

54

Product Testing – The OL 490 offers new options for commercial and industrial product testing, ranging from colormetric evaluation of substances to assessing the performance of optical elements under various operating lighting environments. These applications include on-line/off-line parts inspection, color matching/ rendering, and surface tests.

Instrument/Detector Spectral Response Calibration – Typical monochromators coupled to incandescent sources provide only limited utility in terms of control of spectral content and programmable LED sources offer only limited spectral range and use static spectral filtering within to shape the profile. In comparison, the versatility, accuracy, reliability and speed of the OL 490 are unmatched.

Forensics and Biosciences Imaging – The OL 490 brings new dimensions to tools already in use in clinical and field research. The OL 490 is the ideal source for fluorescence excitation, illumination for microscopy, and other forms of imaging, including fiber-based techniques such as endoscopy. Spectral output can be tailored to stimulate reactions in photosensitive biological systems.

Spectral Synthesis

The OL 490 can easily synthesize complex spectral features that enable simulation of custom filtered source, LEDs, luminaires, day light, night light, and room light. Nearly any spectral shape, natural or synthetic, can be created. For highly precise spectra, adding the optional real-time spectrometer feedback can increase the spectral matching to the target spectra even more.

Software

The OL 490’s control software is both powerful and easy to use. Operators can easily set multiple bands, sweeps, and trigger modes. The OL 490’s software allows direct control of the DLP mirror array to produce almost any desired spectrum. The software control has three (3) primary modes of operation that will render the desired spectral shape: Render Sliders, Render List, and Render Sequence. An SDK is also included to allow for fully customized control.

• Render Sliders Real time manual rendering is easy with the slider controls, which instantly change the wavelength, bandwidth, or intensity by dragging the slider left and right, or entering a value in the text box. The spectral output is updated in real time, useful for manipulation of a single peak. This easily simulates bandpass filters, LEDs, and monochromators.

• Render List For combining multiple peaks, the Render List mode allows the slider controls to send each desired peak to a list that can be selected for composite rendering. The parameters of each individual peak can be edited and updated into the list.

• Render Sequence Spectral patterns may be sent from the list to a sequence inserted at any desired order in time. The sequence can be executed at a user selectable rate. Start, stop, and pause controls control the sequence output timing. The loop can be set for a specific number of cycles then stopped, or set for continuous operation. Hardware triggers also allow precise control for use with other equipment, such as cameras and microscopes.

HSi-300 Hyperspectral Imaging System __________________________________

Gooch and Housego’s patented acousto-optic tunable filter (AOTF) imaging module fulfills the promise of multispectral and hyperspectral imaging through unmatched spectral flexibility and switching speed. The performance capabilities of this technology make it ideally suited for high-content, high-throughput fluorescence studies as well as spectral transmission and reflectance imaging. Potential applications range from live cell and whole animal studies to fixed slide clinical diagnostics.

Multispectral and Hyperspectral Imaging In multispectral and hyperspectral imaging, a series of images of an object are acquired at many different wavelengths so that the complete spectrum of each pixel is available, which is represented as an image cube. Coupled with transmission and fluorescence microscopy techniques, hyperspectral imaging enables fast and quantitative image

analysis.

AOTF technology.

What is an acousto-optic tunable filter (AOTF)? Our patented AOTF is a high-speed, high-throughput random-access solid-state optical filter with an adjustable optical passband and exceptionally high rejected light levels. Gooch & Housego’s proprietary AOTF technology delivers diffraction-limited image quality with variable bandwidth resolution down to within 1.5 nm. Wavelength switching time, including computer control overhead, is a few hundred microseconds. The Gooch and Housego’s HSi-300 Hyperspectral Imaging System features an AOTF-based spectral filter system, instrument driver control and control module, and a powerful, intuitive image capture and hyperspectral analysis software suite. The HSi-300 now features µ-Manager plug-ins, a free and open source application software platform for imaging and control of automated microscopes on multiple operating systems (Windows, Mac, and Linux). µ-Manager offers a flexible and powerful image capture and processing package at no cost to the user. The HSi-300 in integrated with DVC cameras and the Andor iXon EMCCD family of scientific cameras, and soon will be integrated with Hamamatsu and Photometrics.

Applications Powerful image capture and hyperspectral analysis tools facilitate both research tasks and dedicated process applications development.

Biological Research A number of fluorescence microscopy research techniques benefit from the speed and resolution of Gooch and Housego’s hyperspectral imaging technology:

• Immunohistochemistry

• Quantum Dots (Q-Dots)

• Fluorescence in-situ hybridization (FISH)

• Fluorescence resonance energy transfer (FRET)

• Spectral Karyotyping (SKY)

Medical Diagnostics Gooch and Housego’s technology has the potential to take high-content/ -throughput analysis to a new level.

AOTF versus Other Spectral Imaging Techniques While liquid crystal tunable filters (LCTFs) have broad tuning capabilities, their bandwidth is fixed and switching times are typically more that 50 milliseconds with significantly lower throughput that AOTFs. In Fournier transform imaging spectroscopy (FTIS), an interferometer is used to acquire imaging data at a variety of settings, and the resulting data transformed to provide a spectral image set. With FTIS, the choice of wavelengths and bandwidths cannot be changed and all wavelengths have to be captured regardless of application interest, a process that typically takes tens of seconds.

R 0.117384 G 0.455283 B 0.381106


57

In tomographic imaging, light is bounced off of a diffraction grating, separated, and captured on a single CCD chip for subsequent processing and extraction of the spectral information, a slow and computationally intense procedure with limited imaging resolution. Unlike these techniques, AOTFs allow wavelength and bandwidth to be changed at will. It takes less than 100 microseconds to change settings, capabilities that are ideal for high-throughput multiprobe imaging.

Integrating Spheres – OL IS-670-LED ___________________________________ The OL IS-670-LED Integrating Sphere is designed specifically for use with the OL 770-LED High-speed LED Test and Measurement System to provide accurate measurements of many properties of light emitting diodes, and permits the user to make color measurements in accordance to recommendations by NIST and CIE Publication 127. The OL IS-670-LED provides an accurate means of measuring the total spectral luminous flux and total radiant flux of “forward-looking” LEDs. The OL 770-LED Windows

® software provides instant measurement data reduction for such quantities

as:

• Total Radiant Flux (watts)

• Total Luminous Flux (lumens)

• Total Spectral Flux (watts/nm)

• Dominant Wavelength

• Peak Wavelength

• Half-bandwidth

• Color Purity

• Correlated Color Temperature

• Color Rendering Indices

• Chromaticity Coordinates The OL 770-LED/IS-670-LED combination incorporates features such as an internal reference/auxiliary lamp and a nearly perfect cosine response to eliminate major sources of error. The OL IS-670-LED consists of a 6-inch diameter, PTFE coated, high reflectance integrating sphere. It is mounted in a convenient, rugged stand for tabletop or laboratory benchtop use, eliminating the need for mounting rods or fixtures. The sphere has a 90° entrance port to exit port configuration and includes a SMA connector for connection of the auxiliary lamp incorporated into .the OL 770-LED via an optical fiber.

The OL IS-670-LED yields spectral reflectance properties > 99% in the 300 nm to 1700 nm wavelength range. A coated internal baffle in front of the exit port prevents non-integrated light from exiting the sphere. The exit port of the sphere is coupled to the OL 770-LED via a fiber optic cable.

A wide range of off the shelf LED holders is available, as well as custom LED holders for specific device configurations.

INTEGRATING SPHERES

A unique feature of the OL 770-LED/IS-670-LED combination is that it includes an internal reference/auxiliary lamp not found in systems available from other manufacturers. This built-in reference/auxiliary lamp is used to calibrate the integrating sphere and compensate for changes in the spectral efficiency of the integrating sphere due to self-absorption and reflectance properties of LEDs. This provides for accurate on-site calibrations and is so easy to use that inexperienced personnel can perform them. It sharply contrasts with competitor’s systems that need to be shipped back for calibration since:

The exit port has a coated internal baffle that eliminates any non-integrated light from exiting it and holds a removable filter. The auxiliary lamp port also has a coated baffle, which helps to integrate the output of the lamp to the sphere. The complete assembly is mounted in a sturdy aluminum frame. The internal surface and both baffles are coated with Gooch & Housego’s Optolon 2 high reflectance coating. Unlike its predecessor, the OL IS-1800, which opens horizontally, the OL IS-1800H is equipped with a vertical opening. As a result of the design change, the sphere footprint is substantially smaller. Additionally, the horizontally-mounted seam allows for an optional port to be placed on top of the hemisphere for testing downlights.

Integrating Spheres – OL IS-1800/ -3900/ -7600 ___________________________

This series of Large Integrating Spheres is designed for total luminous flux and/or total spectral flux measurement applications. The IS-1800, IS-3900, and IS-7600 have diameters of 18-, 39-, and 75-inches respectively and are coated with the rugged, washable, Optolon 2 Integrating Sphere Spray Coating (see Information Sheet IS17). For total luminous flux measurement applications, the IS-1800, IS-3900 and IS-7600 Integrating Spheres can be obtained as part of a complete measurement system: namely, the IS-1800-TLF, IS-3900-TLF and IS-7600-TLF Total Luminous Flux Measurement Systems.

For total spectral flux measurement applications, the IS-1800, IS-3900 and IS-7600 can be interfaced to the OL Series 754 and OL Series 750 Spectroradiometer Systems. Consult factory for recommended system configurations. The IS-1800, IS-3900 and IS-7600 consist of two hemispheres mounted in a rugged frame equipped with locking casters. The hemispheres separate for ease of opening for installing or interchanging lamps. The sphere design makes provision for using an optional auxiliary lamp. Two standard baffles are included: one located between the lamp to be measured and the exit port and one located in front of the optional auxiliary lamp. These baffles, which

are also coated with Optolon 2, prevent non-integrated incident light from directly reaching the detector port.

Also located inside the sphere assembly is a lamp holder mounting plate. The lamp holder plate facilitates the mounting of various types of lamp holders and sockets. The design of each lamp holder positions the lamp near the relative center of the sphere assembly and includes an additional coated baffle as required by the size of the lamp to be measured.

OL Series 426 Integrating Sphere Calibration Standard ____________________

GENERAL The OL Series 426 Low-Light-Level Calibration Standard is designed for accurately calibrating very sensitive microphotometers, image intensifiers, telephotometers, and imaging spectroradiometers for photometric or spectroradiometric response at moderate to extremely low light levels. It serves as a highly accurate, large area, uniform, diffusely radiating source with a near normal

luminance that can be varied over nearly 6 decades with essentially constant color temperature. The OL Series 426 consists of an Optics Head and a separate electronic display console/power supply (OL 400-C Controller). This enables remote location of either unit, which facilitates alignment or positioning of the source with respect to the device to be calibrated. The source module/optics head is designed such that it can be configured with integrating spheres having diameters of 4, 6, 8, 12 and 18 inches with exit (radiating) ports of 1, 1½, 2, 3 and 6 inches, respectively.

OPTICS HEAD The OL 426 is based on a dual integrating sphere design, with the arrangement of these spheres in series. The exit port of the first sphere, or primary sphere, produces a uniform beam into the entrance port of the secondary sphere. A baffle tube connects the exit port of the primary sphere to the entrance port of the secondary sphere, and an aperture in the baffle tube determines how much light is allowed into the secondary sphere, thus the maximum luminance at the radiating port can range over several decades depending on the size of the aperture installed. The aperture is not used to determine the true luminance at the exit port of the secondary sphere but merely scale it by the desired amount. A precision silicon detector-filter combination with an accurate photopic response mounted in the wall of the primary sphere tracks the luminance in the primary sphere at higher levels for accuracy purposes, and the luminance display is scaled to indicate the actual luminance at the exit port of the secondary sphere. The actual luminance of the exit port is calibrated via measurements, and then the monitor detector gain is scaled appropriately. The in-line sphere port concept with an intermediate spider baffle provides exceptional uniformity in the near normal luminance across the radiating port. A shutter is located between the lamp and the entrance port of the primary sphere. The luminance/ radiance output can be switched between zero and any desired level without adjustment or lamp changes. An optional filter holder, mounted at the exit port, accommodates alignment targets, filters, de-coupling diffusers etc. for specific user requirements. Spectral shaping filters can be utilized to simulate various sources such as Illuminate A, B, C, D65, etc. In addition to luminance and color temperature, the OL Series 426 can be obtained with calibrations for spectral radiance over the 350 to 1100 nm wavelength range.

RADIANCE/ LUMINANCE STANDARDS

63

CONTROLLER The microprocessor-based OL 400-C Controller performs all system interface and monitoring functions. An automatic ramp up/down function eliminates potentially dangerous current surges to the lamp. Luminance, color temperature, and lamp current are displayed on a 2 line by 20 character alphanumeric LED display, which may be turned off for low-light level conditions. An 8-key keypad and main power switch are located on the front panel for easy access to all system functions. Luminance is displayed with 4 ½ digits plus exponent in units specified by the user. As an option, the display can be factory programmed to read in virtually any pertinent units the user desires. DC current supplied to the lamp has a 0.001 ampere resolution with a 0.02% uncertainty. The controller computes the color temperature of the source over the range of 2000 – 3000K. Software for remote operation of the source is provided, allowing control of lamp on/off functions and setting the lamp current (color temperature) as well as readout of the photometer in any preprogrammed optical unit. An optional software development kit is available for custom programming.

GENERAL The OL Series 454 Integrating Sphere Source is designed to produce a high intensity Lambertian distribution. It is useful as a highly uniform illumination source for contrast measurements, linearity tests, flat-fielding of devices for response uniformity, and device MTF with the optional filter holder and the desired resolution target. It consists of an OL Series 454 Optics Head and a separate OL 53 Constant Current Source. The source is also available with a color temperature calibration over the 2000 – 3000K range. The source module/optics head is designed such that it can be configured with integrating spheres having diameters of 4, 6, 8, 12 and 18 inches with exit (radiating) ports of 1, 1½, 2, 3 and 6 inches, respectively.

SOURCE MODULE / OPTICS HEAD The Source Module/Optics Head uses a 150-W tungsten-halogen reflectorized lamp with a micrometer-controlled variable aperture between the lamp and the integrating sphere. The variable aperture can be used to attenuate the output of the sphere source over a range of up to six decades. The sphere has a highly reflective, diffuse reflecting PTFE based coating.

OL Series 457 LED Integrating Sphere Calibration Standard________________

The OL 457 LED Integrating Sphere Calibration Standard is a cost-effective, wavelength-selectable, nearly monochromatic NIST-traceable radiant light source. It provides more flexibility and higher performance than filtered sources and is a significantly lower cost alternative to monochromators. Typical applications include anywhere a stable or calibrated source is required, e.g. MTF, radiance and irradiance sensitivity of detectors, arrays and cameras, linearity testing,

dynamic range testing, signal-to-noise testing etc.

Interchangeable LED sources offer more versatility, affording users with an unprecedented level of uniformity and accurate continuously variable intensity over many decades. The interchangeable LED modules are easily installed and removed from the optics head without affecting calibration accuracy. These fully integrated source and heat sink assemblies offer long life and high thermal efficiency for increased stability and output.

The OL 457 consists of an optics head and a separate precision constant current source (OL 401-C Controller). This enables remote location of either unit, which facilitates alignment or positioning of the source with respect to the device to be calibrated. The source module/ optics head is designed such that it can be configured with integrating spheres having diameters of 4, 6, 8, 12, and 18 inches.

The OL 401-C Calibration Standard Controller automatically recognizes installed LED modules and provides the appropriate precision current to the LEDs, readout of LED current, amplification of the detector signal, and readout of the radiance.

GENERAL

The OL Series 466 Automated Low-Light-Level Integrating Sphere Calibration Standard is designed for accurately calibrating very sensitive instruments such as microphotometers, telephotometers, image intensifiers, and imaging spectroradiometers for photometric, radiometric, or spectroradiometric response at moderate to extremely low light levels. It serves as a highly accurate, large area, uniform, diffusely radiating source with a near normal luminance that can be varied over decades with essentially constant color temperature.


72

The OL Series 466 consists of an optics head and a separate microprocessor controlled luminance display/lamp power supply/motor controller console (OL 462-C Controller). This enables remote location of either unit, which facilitates alignment or positioning of the source with respect to the device to be calibrated. The source module/optics head is designed such that it can be configured with integrating spheres having diameters of 4, 6, 8, 12 and 18 inches with exit (radiating) ports of 1, 1½, 2, 3 and 6 inches, respectively.

OPTICS HEAD

The OL 466 is based on a dual integrating sphere design, with the arrangement of these spheres in series. The exit port of the first sphere, or primary sphere, produces a uniform beam into the entrance port of the secondary sphere. A baffle tube connects the exit port of the primary sphere to the entrance port of the secondary sphere, and an aperture in the baffle tube determines how much light is allowed into the secondary sphere, thus the maximum luminance at the radiating port can range over several decades depending on the size of the aperture installed. The aperture is not used to determine the true luminance at the exit port of the secondary sphere but merely scale it by the desired amount. A precision silicon detector-filter combination with an accurate photopic response mounted in the wall of the primary sphere tracks the luminance in the primary sphere at higher levels for accuracy purposes, and the luminance display is scaled to indicate the actual luminance at the exit port of the secondary sphere. The actual luminance of the exit port is calibrated via measurements, and then the monitor detector gain is scaled appropriately via a calibration factor programmed into memory. The optics head has a 150-W tungsten-halogen, reflectorized lamp with a motorized, computer controlled, variable aperture between the lamp and the entrance port of the primary sphere. This combination provides for continuous adjustment of the sphere luminance over a range of more than 10

6, which is tracked and displayed by the OL 462-C

Controller. The in-line sphere port concept with an intermediate spider baffle provides for exceptional uniformity in the near normal luminance across the radiating port. A motorized, computer-controlled shutter is located between the lamp and the entrance port of the primary sphere. The luminance/ radiance output can be switched between zero and any desired level without adjustment or lamp changes. An optional filter holder mounted at the exit port accommodates alignment targets, filters, de-coupling diffusers, etc. for specific user requirements. Spectral shaping filters can be utilized to simulate various sources such as illuminates A, B, C, D65, etc. In addition to luminance and color temperature, the OL Series 466 can be obtained with calibration for spectral radiance over the 350 to 1100 nm wavelength range. The microprocessor based OL 462 Controller performs all the system interface and monitoring functions. An automatic ramp up/ down function eliminates potentially dangerous current surges to the lamp. Luminance, color temperature, lamp current and operational prompts are displayed on a two line by 20 character alphanumeric vacuum-fluorescent display. A 20-key keypad, rotary encoder knob, and main system power switch are also located on the front panel for easy access to all system functions. Luminance is displayed with 5 digit resolution in units specified by the user. As an option, the display can be factory programmed to read out in virtually any pertinent units the user desires. The Controller computes the color temperature of the source and displays lamp current or color temperature over the range of 2000 to 3000K. The luminance, color temperature, and lamp current can also be set by an external computer via the standard RS-232C interface. RS-422 and GPIB (IEEE-488) interfaces are also available. An internal microprocessor controlled lamp timer enables the user to track the number of hours the lamp has been in operation.

OL Series 468-39 Integrating Sphere Calibration Standard _________________

GENERAL

The OL 468-39 Automated Integrating Sphere Calibration Standard is a large area source designed for accurately calibrating instruments such as microphotometers, telephotometers, image intensifiers, cameras, and imaging spectroradiometers that require a source with uniform luminance over a wide field of view. It serves as a highly accurate, large area, uniform, diffusely radiating source with a luminance that can be varied over a range of up to six decades with essentially constant color temperature. The OL Series 468 consists of a motorized source module (Optics Head) and a microprocessor controlled radiometer/lamp power supply/motor controller (OL 462-C Controller). The sphere is mounted into a rugged support frame with locking casters.

OPTICS HEAD

The Optics Head has a 150-W tungsten-halogen, reflectorized lamp with a motorized microprocessor-controlled variable aperture between the lamp and the entrance port of the integrating sphere. This combination provides for continuous adjustment of the sphere luminance over a range of up to six decades. A precision silicon detector/ filter combination with an accurate photopic response is mounted in the sphere wall and monitors the sphere luminance. All internal surfaces of the sphere are coated with Optolon 2, a durable, hydrophobic, highly reflective diffuse coating. An opal diffuser is mounted at the sphere entrance port to provide uniform illumination of the sphere wall, resulting in exceptional uniformity over a 130 degree field of view at the sphere exit port. The near normal (spatial) uniformity of the exit port is excellent as well. An SMA connector is located adjacent to the monitor detector to allow monitoring of the sphere output with an external fiber coupled device. A motorized microprocessor-controlled shutter is located between the lamp and the entrance port of the integrating sphere. The luminance/ radiance output can be switched between zero and any desired level without adjustment or changes to the lamp. An optional filter holder mounted at the exit port accommodates alignment targets, filters, etc. for specific user requirements. Spectral shaping filters can be utilized to simulate various sources such as standard CIE illuminants. In addition to luminance and color temperature, the OL 468-39 can be obtained with a spectral radiance calibration over all or part of the 350 to 1100 nm wavelength range.

CONTROLLER

The microprocessor-based OL 462 Controller performs all the system interface and monitoring functions. An automatic lamp current ramp up/down function eliminates potentially dangerous current surges to the lamp. Luminance, color temperature, lamp current, and operational prompts are displayed on a 2 line by 20 character alphanumeric vacuum-fluorescent display. A 20 key keypad, rotary encoder knob, and main system power switch are also located on the front panel for easy access to all system functions. Luminance is displayed with 5 digit resolution in units specified by the user. As an option, the display can be factory programmed to read in virtually any pertinent units the user desires. DC current supplied to the lamp has a 0.001 ampere resolution with a 0.05% uncertainty. The controller computes the color temperature of the source and displays lamp current or color temperature over the range of 2000 to 3000K. The luminance, color temperature, and lamp current can also be set by an external computer via the standard RS-232C interface. RS-422 and GPIB (IEEE-488) interfaces are also available. An internal microprocessor controlled elapsed time meter tracks the number of hours the lamp has been in operation.

OL Series 480 Variable Temperature Blackbody Calibration Standard________

The OL 480 Blackbody Calibration Standard provides an accurate, high temperature (100° to 1200°C) source of infrared radiation. It is specifically designed for calibrating infrared radiometric and spectroradiometric measurement systems.


76

The blackbody features a unique, uniformly heated recessed cone cavity with an emissivity of 0.99 ± 0.01. Accuracy of calibration is ensured by the use of a NIST-traceable platinum vs. platinum 10% rhodium thermocouple. An 8-position aperture wheel provides a convenient means of controlling the flux radiated by the blackbody (Table 1). The small aperture sizes enable the source to be used as a point source target at a finite working distance, while the larger apertures allow direct calibrations for radiance.

A convenient microprocessor-based, self-tuning digital PID controller holds the selected temperature to within ± 0.05% of full scale. The controller has dual displays with the lower display indicating the desired set point and the upper display indicating the actual blackbody source temperature. The OL 480 can also be coupled to the OL 740-4P Off-Axis Parabola Telescope for obtaining a highly collimated, infrared source of radiant flux.

OL 200 Calibration Standard



OL 200/ 220 / 245 High Accuracy Standard of Spectral Irradiance ___________

Gooch and Housego offers 1000-W DXW, 200-W, and 45-W lamps as standards of spectral irradiance, total irradiance, illuminance, and color temperature. These lamps have tungsten coiled-coil filaments enclosed in a small quartz envelope. The lamp standards can be obtained with spectral irradiance calibrations over all or part of the 250 to 2500 nm wavelength region. In addition, the 1000-W DXW and 200-W lamps can be calibrated out to 4500 nm.

The spectral irradiance standards issued by Gooch and Housego are based on the National Institute of Standards and Technology (NIST) Spectral Irradiance Scale for the wavelength range of 250 to 2400 nm and on a blackbody for the wavelength range above 2400 nm. The NIST Scale has an uncertainty (k=2) of 0.63% in the visible, 1.56% in the ultraviolet at 250 nm, and 0.31% in the infrared at 2000 nm.

Calibration of the 1000-W DXW and 200-W lamps over the wavelength range of 250 to 2400 nm are available with two levels of accuracy: high-accuracy and super high-accuracy. The High-Accuracy Standards of Spectral Irradiance issued by Gooch and Housego have a transfer uncertainty (k=2) relative to the NIST Scale of ± 1-2%. The Super High-Accuracy Standards have a transfer uncertainty relative to the NIST Scale of ± 0.5%.

Method of Calibration

The instrumentation and methods used by Gooch and Housego to transfer calibrations from a standard of spectral irradiance to an uncalibrated lamp is patterned after that used at NIST. The measurement procedure employs the highly accurate wavelength-by-wavelength method of comparison (Figure 1). This minimizes the errors associated with setting the lamp current, distance, wavelength, and repeatability.

In this technique, both lamps (standard and test) are operated at the same distance. The spectral irradiance of both lamps is measured at a set wavelength by translating the double monochromator along the optical bench to view each source. A wavelength-by-wavelength comparison is made at all of the NIST calibration wavelengths.

The High-accuracy Standards are calibrated by comparison to a standard that was calibrated directly against a NIST standard. The Super High-Accuracy Standards are compared directly to a NIST standard

Optional Accessories

Gooch and Housego offers several accessories to enable the user to realize the high accuracy assigned to its NIST-traceable standards. These accessories are designed to minimize errors due to current setting, alignment, and orientation.

The OL 410 and OL 83A Programmable DC Current Sources are specifically designed for operating the lamp standards at the exact calibration current. (See Bulletin 121 for further details).

There are six dimensional variables involved in the NIST recommended alignment of a lamp relative to the instrument. The OL 56, OL 57, and OL 57W Lamp Holders and OL 63 Adjustable Lamp Holder Mount (Figure 2) are designed to allow the user to control the physical positioning of the lamp including distance, horizontal distance, vertical distance, pitch (tilt), yaw (rotation), and roll

OL 220/275/245 Total Spectral Radiant Flux & Total Luminous Flux Stanrdards _____

Gooch and Housego offers 200-W, 75-W, and 45-W lamps as standards of total spectral radiant flux and total luminous flux. These lamps have tungsten coiled and coiled-coil filaments enclosed in a quartz envelope. The lamp standards can be obtained with total spectral radiant flux calibrations over the 250 nm to 1100 nm wavelength region. The total luminous flux is also provided for the spectral standards. The total spectral radiant flux and total luminous flux standards issued by Gooch and Housego are based on the National Institute of Standards and Technology (NIST) Total Spectral Radiant Flux Standard Lamps for the wavelength range of 360 nm to 830 nm. Spectral values provided below 360 nm or above 830 nm are based on NIST FEL 1000-watt Lamp Standard of Spectral Irradiance. The NIST Scale has relative expanded uncertainty (k=2) of ±1.5% at 380 nm, 1.0% at 650 nm, and 0.47% in the infrared at 900 nm.

Calibration of the Total Spectral Radiant Flux Standards over the wavelength range of 380 nm to 830 nm have an estimated transfer uncertainty (k=2) relative to the NIST Scale of ± 2%. The transfer

uncertainty below 360 nm or above 830 nm is estimated to be ± 3% relative to the NIST Spectral Irradiance Scale

The total luminous flux value was verified using a Gooch & Housego integrating sphere of suitable diameter equipped with an internal lamp mount, auxiliary lamp, high accuracy photometric detector, constant current source and OL 730C Programmable Radiometer/Photometer.

Optional Accessories Gooch and Housego offers several accessories to enable the user to realize the high accuracy assigned to its NIST-traceable standards. These accessories are designed to minimize errors due to current setting, alignment, and orientation.

The OL 410 Precision Current Source is specifically designed for operating the lamp standards at the exact calibration current. (See Bulletin 121 for further details). The OL 57W-S (OL 220), OL 57-S (OL 245) and OL E10 (OL 275) Lamp Holders are designed to place the lamp at the correct optical height in the integrating sphere. The plug-in design of the lamp holders allows the user to quickly switch lamp fixtures during testing.

OL FEL High Accuracy Irradiance Standard _____________________________ Gooch and Housego offers 1000-W FEL type lamps as standards of spectral irradiance, total irradiance, Illuminance, and color temperature. These lamps have a tungsten coiled-coil filament enclosed in a small quartz envelope. The lamp bases have been converted to a medium bi-post base as recommended by the National Institute of Standards and Technology (NIST). This special lamp base improves alignment accuracy, which minimizes uncertainties due to positioning and orientation of the lamp. The spectral irradiance standards issued by Gooch and Housego can be obtained with spectral irradiance calibrations over all or part of the entire 250 to 4500 nm wavelength region. Calibrations are based on the NIST Spectral Irradiance Scale for the wavelength range of 250 to 2400 nm and on a copper freezing point blackbody for the wavelength range above 2400 nm. The NIST Scale has an uncertainty of 1% in the visible, 2.5% in

the ultraviolet at 250 nm, and 3% in the infrared at 2000 nm.

Calibrations over the wavelength range of 250 to 2400 nm are available with two levels of accuracy: high-accuracy and super high-accuracy. The High-accuracy FEL Standards issued by Gooch and Housego have a transfer uncertainty relative to the NIST Scale of ± 1%. The Super High-accuracy FEL Standards have a transfer uncertainty relative to the NIST Scale of ± 0.5%.

Method of Calibration The instrumentation and technique used by Gooch & Housego to transfer calibrations from a standard of spectral irradiance to an uncalibrated lamp is patterned after that used at NIST. The measurement procedure employs the highly accurate wavelength-by-wavelength method of comparison (Figure 1). This minimizes the errors associated with setting the lamp current, distance, wavelength, and repeatability. In this technique, both lamps (standard and test) are operated in series at the same current and at the same distance. The spectral irradiance of both lamps is measured at a set wavelength by translating the double monochromator along the optical bench to view each source. A wavelength-by-wavelength comparison is made at all of the NIST calibration wavelengths.

OL 100 Solar Constant Irradiance Standard _____________________________ General The OL 100 is a high-intensity standard consisting of a 1000-watt, DXW, tungsten-halogen lamp mounted in a slip-cast, fused silica reflector. The source has an effective radiating area of 3 x 5 cm. At a distance of 40 cm, the total irradiance is on the order of one solar constant (approximately 136 mW/cm

2). Uniformity tests performed on a

number of these units show that the irradiance in the specified direction over an area of

4 cm2 is uniform to ± 0.25%.

OL UV-40 Ultraviolet Irradiance Standard _______________________________

The OL UV-40 consists of a stable, 30-watt deuterium lamp with an ultraviolet transmitting suprasil window. The lamp is calibrated for spectral irradiance over the wavelength range of 200 nm to 400 nm. The OL UV-40 serves as a convenient, accurate standard for calibrating UV radiometers and spectroradiometers, or it can be used as a known source of spectral irradiance in various UV exposure tests. The deuterium lamp is especially suited for use as an ultraviolet standard since it emits a line-free continuum in the 200 to 400 nm region. Emission is strongest at 200nm, where most instrument sensitivities are low, and weakest in the visible and infrared (which reduces stray-light problems). At 250 nm, the calibrated irradiance value for the OL UV-40 is approximately 5 times greater than the 1000-watt tungsten lamp standards of spectral irradiance. Spectral irradiance values are reported in tabular form every 10 nm from 200 to 400 nm. Typical spectral irradiance curves for the OL UV-40 and 1000 W tungsten lamp standards are shown for comparison. Calibration of the OL UV-40 over the range of 250 to 400 nm is based on the National Institute of Standards and Technology (NIST) high-accuracy standards of spectral irradiance. Calibrations

over the range of 200 to 250 nm are based on NIST deuterium lamp standard of spectral radiance. The instrumentation used by Gooch & Housego to transfer calibrations from a standard lamp to a test lamp is patterned after that at NIST. The measurement technique employs the highly accurate wavelength-by-wavelength method of comparison with both lamps operating at a set DC current of 300 mA. The uncertainty in the spectral irradiance values for the OL UV-40 varies from 3 to 5% from 400 to 250 nm and is 10% below 250 nm. Prior to calibration, each lamp is seasoned for 24 hours. Stability tests indicate that after the initial

burn-in, the irradiance generally remains constant to within ± 2% for a period of 50 hours use. The aging of the standard is not a function of the shelf life. Although the basic OL UV-40 is calibrated for spectral irradiance, the standard can also be obtained with a calibration for spectral radiance. A typical standard has a radiance of 12 W/(m

2 nm sr) at 250 nm. The calibration area is

approximately 0.3 mm in diameter.

OL 752-10 & -12 Plug-in Standards of Spectral Irradiance __________________

Two plug-in, pre-aligned irradiance standards are available for accurately calibrating the OL 754 Spectroradiometer for spectral irradiance response. The "plug-in/ pre-aligned" concept eliminates tedious and time consuming set-up and alignment normally associated with spectroradiometric standards as they merely attach to the OL 754's integrating sphere cosine receptor. Both standards, with appropriate baffles, are mounted in pre-aligned/holder mounts. Machined, cylindrical covers are provided to protect the lamps when not in use.

OL 752-10 Tungsten Plug-In Standard

The OL 752-10 can be obtained with spectral irradiance calibrations over the wavelength range of 250 to 2500 nm. It consists of a compact, 200-W tungsten-halogen lamp operating at a color temperature of about 3000 K. The short working distance of 13 cm results in irradiance levels significantly higher than that normally obtained with higher wattage standards. The combination of greater precision in optical alignment and higher irradiance levels provides for a more accurate calibration of the spectroradiometer. Calibration of the OL 752-10 is based on the NIST High-Accuracy Scale of Spectral Irradiance. The NIST Scale has a reported uncertainty that varies from ± 2% at 250 nm to ± 1% in the visible. The OL 752-10 has a transfer uncertainty relative to the NIST Scale that varies from ± 1.5% in the

ultraviolet to ± 1% in the visible-near infrared.

OL 752-12 Deuterium Plug-In Standard

The OL 752-12 is calibrated for spectral irradiance over the wavelength range of 200 to 400 nm. It uses a stable, 40-W deuterium lamp. When mounted in the plug-in/pre-aligned housing, the working distance is 10 cm. This short working distance generates considerably higher irradiance levels than that obtained with conventional ultraviolet irradiance standards. The OL 752-12 is calibrated relative to the NIST Ultraviolet Irradiance Standard for the region below 250 nm and to the NIST High-Accuracy Scale of Spectral Irradiance for the 250 to 400 nm region. The NIST Ultraviolet Irradiance Standard has an uncertainty that varies from ± 7.5% at 200 nm to ± 5% at 250 nm. The OL 752-12 has a transfer uncertainty relative to the NIST Scales that varies from ± 3% at 200 nm to ± 1.5% at 400 nm.

OL 345 Radiometric & Photometric Calibration Standard __________________

GENERAL

The OL 345 Calibration Standard consists of a 45-watt tungsten-halogen lamp and a removable 2-inch diameter flashed-opal diffuser mounted in an air-cooled, machined, cylindrical housing. With the diffuser in place, the uniform, 15.5 cm² radiating source serves as a standard of spectral radiance over the wavelength range of 350 to 1100 nm and as a standard of luminance. When the diffuser is removed, the OL 345 serves as a standard of spectral irradiance from 250 to 2500 nm and as a standard of illuminance. The OL 345 can also be obtained with the source operating at a specified color temperature.

A filter holder is provided for inserting 2-inch square filters into the unit between the lamp and the diffuser. Spectral shaping filters for simulation of various types of CRT phosphor screens and for obtaining color temperatures up to 6000 K are available. Narrow band interference filters for obtaining discrete spectral radiances and irradiances are also available.

APPLICATION

The OL 345 is a rugged, versatile radiometric and photometric standard capable of accurately calibrating a large variety of light measuring instrumentation. When the 2-inch diameter opal diffuser is attached, the unit is ideal for calibrating such instrumentation as tele-photometers, microphotometers, telespectro-radiometers, etc. When the opal is removed, the absolute calibration of spectral irradiance and illumination measuring instrumentation is easily accomplished. The ability to insert either narrow band interference filters or spectral shaping filters in the beam enables the calibration of various radiometers and photometers to be made quickly and accurately.

OL 83A Programmable Current Source _________________________________

The OL 83A is a microprocessor-controlled, precision DC current source specifically designed to accurately operate tungsten filament lamp standards and calibration sources. The power output range is 10 to 1000 watts. The unit features:

• Output current accuracy of ± 0.01% or better

• Controlled ramp up/ ramp down of the lamp current

• Simultaneous digital readout of lamp current, voltage, and power

• Ability to set lamp current, voltage, or power

• Lamp "library" for storing and recalling the operating parameters & description for up to 10 different lamps. The user-defined operating parameters include lamp current, voltage or power, current limit, calibration due interval & lamp hours. A separate elapsed time meter keeps track of the lamp hours for each of the 10 lamps. A calibration due warning message will appear upon power up when the lamp hour’s limit is exceeded and/or one (1) year has elapsed since last calibration.

• RS-232 (standard) and IEEE-488 (optional) computer interface Tungsten lamp standards must be operated at their specified calibration current in order to realize the accuracy of the standard. A small error in setting the lamp current can induce a sizeable, wavelength dependent error in the spectral output of the lamp. The OL 83A enables the lamp current to be set to an accuracy of better than ± 0.01%, a factor of about 25 better than most other commercial power supplies, which are typically 0.25%. The advantage of the OL 83A's increased accuracy is illustrated in the table below. In order to eliminate electrical shocking of the lamp due to high initial current surges, a ramp function is used to control the turn-on current rise. Once the instrument is turned on, the current automatically increases at a slow, safe rate until the set current is reached. A fail-safe, shut down circuit protects the lamp standard against any equipment malfunctions. The current sources will maintain their accuracies while experiencing ± 10% fluctuations in line voltage and ±10% variance on the load voltage. These features effectively compensate for transients in the power line and variations in resistance from one lamp to another. The power supplies are packaged in a chassis suitable for mounting in a 19" cabinet rack.

The OL 46D Current Source for Deuterium Lamps is specifically designed to operate the OL UV-40 and OL 752-12 deuterium lamp standards of spectral irradiance. The OL UV-40 must be operated at the same current used during the calibration in order to realize the calibration accuracy. Accordingly, the OL 46D provides a constant lamp current of 300 mA with an uncertainty of ± 0.1%. It is also an ideal current source for the OL 740-20 and OL 750-20 deuterium sources. The OL 46D features complex automatic lamp starting and operating supplies. Its dual filament design can operate lamps

with high or low filament current requirements. When the supply is turned on, a current is supplied to the starting filament. After 20 seconds, the regulated filament current is reduced 40% of the initial value and the high voltage circuit is switched on. Following the high voltage pulse, the lamp arc strikes and a precision lamp current is established. The circuit is designed to provide a stable, reliable discharge without subjecting the lamp to undue stress. The OL 46D regulated power supply maintains its accuracy during power line transients of ± 10%. The supply will also operate over a ± 10% load variance, which allows it to accommodate different operating voltages from one lamp to another.

Calibration & Measurement Services ___________________________________ Gooch & Housego was established as an optical radiation instrumentation, standards and calibration laboratory in 1970. Forming the nucleus of the company were two former NIST (National Institute of Standards and Technology, formerly the National Bureau of Standards) physicists who had individually made significant contributions to the field of spectroradiometry and electro-optical technology. The company was established to eliminate a void that existed in industry, government, and academia in the area of optical radiation standards, calibration services, and measurement instrumentation. As the result of a constant emphasis on precision and accuracy in these endeavors, the company has earned a worldwide reputation for high quality instrumentation and unique solutions to the most difficult and complex light measurement challenges. The key to Gooch & Housego’s capabilities lies in the nearly 100 collective years in light measurement accumulated by senior personnel. The contributions to optical radiation measurement by the company’s former resident scientist alone, Dr. Richard Young, span more than 30 years. Other key personnel’s education, involvement in industry organizations, and hands-on experience make them among the most respected professionals in this field. Though initially patterned after the procedures of NIST laboratories, Gooch & Housego has evolved its practices more toward handling practical calibration problems. As a result, the company provides unique calibration services that include, but are not limited to, providing spectroradiometric, radiometric and photometric standards.
