Borescopes
A borescope is a device for the internal inspection of hard-to-get-at mechanical parts, such as rifle barrels, sewer pipes, oil wells, or gas mains. The long narrow tube used contains a telescope system with as many relay lenses as necessary. A lamp located in front illuminates the inside of the bore, and the inclusion of a small 45° mirror often permits detailed examination of the tube wall. Some small borescopes and most types of medical endoscopes are now equipped with a fiber optic bundle, for image and/or illumination transfer.
