Borescope
The optical system is usually surrounded by optical fibers used for illumination of the remote object and a rigid or flexible protective outer sheath. The remote object is illuminated and an internal image formed by the objective lens is relayed to the eyepiece which magnifies the internal image and presents it to the viewer’s eye. Borescopes are used for inspection work where the area to be inspected is inaccessible by other means. Borescopes are commonly used in the visual inspection of aircraft engines, aeroderivative industrial gas turbines, steam turbines, diesel engines and automotive/truck engines. Gas and steam turbines require particular attention because of safety and maintenance requirements. Borescope inspection of engines can be used to prevent unnecessary maintenance, which can become extremely costly for large turbines. They are also used in manufacturing of machined or cast parts to inspect critical interior surfaces for burrs, surface finish or complete through holes. Forensic applications in law enforcement and building inspection are also common uses for borescopes.
