Features & Benefits
Inspect by viewing images from areas
Invisible to naked eye
Cavities difficult to access may be easily
and accurately observed
Can be inspected During Normal Downtime

Rigid Borescopes
![Page 6: Industrial Endoscopes](https://reader034.fdocuments.us/reader034/viewer/2022051513/5464bc9db4af9f7f4f8b4883/html5/thumbnails/6.jpg)
RIGID BORESCOPES
Combines Conventional Lenses With Short Optical-Glass Rods
![Page 7: Industrial Endoscopes](https://reader034.fdocuments.us/reader034/viewer/2022051513/5464bc9db4af9f7f4f8b4883/html5/thumbnails/7.jpg)
Rigid Borescope - Dimensions
Wide range of Diameters & Lengths
1.6 mm to 10 mm Diameter
50 mm to 1500 mm Length
![Page 8: Industrial Endoscopes](https://reader034.fdocuments.us/reader034/viewer/2022051513/5464bc9db4af9f7f4f8b4883/html5/thumbnails/8.jpg)
Choosing A Borescope
Choose by physical Trials with the Component
Choose Diameter, Length, Viewing Angle & Field of View for
Optimum Selection.
Borescope must allow "wiggle room” inside the hole
Too Small Dia may not give Sufficient Area of Coverage
![Page 9: Industrial Endoscopes](https://reader034.fdocuments.us/reader034/viewer/2022051513/5464bc9db4af9f7f4f8b4883/html5/thumbnails/9.jpg)
Choosing A Borescope
Diameter: 3.3 mm Borescope will be optimum for 5 mm Bore but
may not be optimum for a 12 mm bore where 8 mm will be
optimum
Length: Choose a Borescope to penetrate to the greatest depth
required, but not so long as to be unwieldy outside the hole
![Page 10: Industrial Endoscopes](https://reader034.fdocuments.us/reader034/viewer/2022051513/5464bc9db4af9f7f4f8b4883/html5/thumbnails/10.jpg)
Direction-of-View (DOV)
Axis of the center to the field-of-view
![Page 11: Industrial Endoscopes](https://reader034.fdocuments.us/reader034/viewer/2022051513/5464bc9db4af9f7f4f8b4883/html5/thumbnails/11.jpg)
Direction-of-View (DOV)
![Page 12: Industrial Endoscopes](https://reader034.fdocuments.us/reader034/viewer/2022051513/5464bc9db4af9f7f4f8b4883/html5/thumbnails/12.jpg)
Direction-of-View (DOV)
Object straight ahead - 0° DOV might be Best
Object very close to the entry port (Engine Valves near a
spark plug hole) a backward-looking 120° Borescope might
be Best
When examining a bore, like a rifle barrel, a 90° DOV will
be perfect.

CCD - What is it ?
Used in what are known as CCD camera
Special Piece of Silicon Called a Charge Coupled Device
or CCD
This silicon wafer is a solid-state electronic component, which
has been micro-manufactured and segmented into an array of
individual light-sensitive cells called "photosites."
Each photosite is one element of the whole picture that is
formed, thus it is called a picture element, or "pixel."
