As its name suggests, a borescope can inspect things through a hole. Rigid borescopes are ideal when straight-line access to the inspection site is required, particularly when only narrow access is available. Borescopes are used to inspect aircraft engines, turbines, wall cavities, weapon systems and fuel injectors, and can be used as predictive maintenance tools.

They use an optical system to transmit an image from the lens at the inspection area back to the eyepiece. In some instances a still or video camera can be mounted on to the eyepiece to allow the inspection to be visually documented. The inspection area can also be illuminated by adding a fibre bundle which relays light from an external source.

The rigid nature of a borescope ensures that they provide a high-quality image with little distortion. Instrument diameters range from 0.9 mm (0.03 in) to 16 mm (0.6 in) with working lengths of up to 1.5 m (4.9 ft), although longer lengths are possible using extension tubes.

Some borescopes offer a greater field of vision by attaching the lens to a swing prism. This can allow the user to adjust the direction of view from 55º to 115º and inspect a greater area in a shorter space of time.

Borescopes are easy to use and as a result they offer a straightforward inspection solution with minimum set-up.
