Clever use of digital cameras in combination with intensifiers and boosters allow us to create images of high-speed events, even when light is failing. In addition, fast gating offers possibilities to record multiple images in one frame. For creating images of events that are invisible to the human eye, like infrared and UV, radiation conversion techniques can be used. Lambert Instruments supplies both intensified High Speed Cameras the HiCAM series and High Speed Intensifier Attachments (HiCATT) which can be lens coupled to regular high speed cameras

First stage: Photons converted to electrons, accelerated and then multiplied in the MCP. The electron clouds get converted back to photons at anode screen. Second stage: Photons converted to electrons, accelerated and converted back to photons at anode screen.

Intensifier ConfigurationsAvailable configurations for both HiCATT and HiCAM: ■ High quality image intensifier with added booster for maximum output brightness. 1st stage intensifier: Gen 2 or Gen 3 2nd stage intensifier: Gen 1 with high output brightness■ Spectral responses from UV to NIR (see chart) Gen 2: S20, S25, Broadband Gen 3: GaAsP, GaAsP enhanced red, GaAs■ Sensitivity 0.0001 lux

■ Phosphor P46: 0.2-0.4 µs decay time to 10% P43, P24 and P20 available on request ■ MCP: single or dual ■ Luminance gain first stage: up to 30.000 lm/m2/lux■ Gain second stage: 10x■ Standard gating down to 40ns ■ Fast gating: Gen 2: 3 ns Gen 3: 5 ns

HiCAM High Speed Intensified CameraThe HiCAM series Cameras offer the unique combination of high-speed and sensitivity down to single photon level. These properties are achieved by using a dual stage image intensifier that is fiber-optically coupled to the CMOS sensor. Depending on the specific application the spectral sensitivity can be selected.

Key Features ■ Fibre optically coupled high quality Gen 2 / Gen 3 image intensifier with added booster for maximum output brightness■ Fast gating downto 3ns■ Spectral response from UV to NIR■ Standard F-mount or C-mount input■ Smart framing technology■ Fiberoptically coupled■ Gigabit Ethernet Interface■ Up to 16 GB internal memory■ User friendly software■ Extensive software package for camera/intensifier control, image viewing and image storage■ SDK and LabView driver available

HiCATTHigh Speed Intensified Camera attachmentThe HiCATT is specially designed for use in combination with high-speed cameras. It amplifies low-light-signals to a level that is up to 100.000 times higher. The HiCATT is standard equipped with an hybrid Image Intensifier consisting of 2 stages. The first stage, a Gen 2 / Gen 3 proximity focused MCP intensifier, offers a very high, adjustable gain. The second stage, a Gen 1 booster, produces the extra high output brightness that is required for high speed imaging. An integrated relay lens couples the image intensifier to the camera. Depending on the size of the image sensor different relay lenses are applied.

■ For use in combination with Hi-Speed cameras operating at speeds up to 300.000 fps (2.5 MHz in burst mode)■ Wide selection of image intensifiers (see configurations)■ Up to 25mm output image diameter, matching with the larger

high-speed image sensors■ Standard C-mount or F-mount input and output■ Intensifier Diameter: 18 mm, 25 mm■ Control : TTL Gating input, manual Gain control S: Standard Digital Interface, USB D: Digital Delay Generator, Low Jitter■ Relay lens: 1:1, 2:1■ Mount: F-mount, C-mount■ Gate pulse frequency (kHz) DC –300 kHz ■ Triggering: TTL, switch, rising or falling edge, on image content variation

Application Examples The recording a blue gas flame from e.g. a Bunsen burner at high

frame rates poses a challenge. The light intensity of the flame is not that high and to be able to see any details, especially in close-ups, you need very short exposure times.

1a. Recording made with a standard high speed camera at 1000fps and 1ms exposure time. On the one side a longer exposure time is needed to increase the sensitivity of the camera. On the other side a shorter exposure time is needed to prevent motion blur.

1b. Recording made with the HiCATT in front of the high speed camera at 2000fps and 15µs exposure time (using gating). The HiCATT makes it possible to capture flames at frame rates up to 300.000fps. By using gating fast electro-optical shutter function of the image intensifier) the exposure time can be limited to a value at which motion blur is no longer an issue.

2. Recording sequence made with the HiCATT in combination with a high speed camera. The recording shows a combustion cycle of a fuel injection engine at 22.000 fps.
