ABSTRACT:
A special endoscope for examining the structure of surfaces of measuring sites in narrow gaps formed in parts to be inspected includes a sword-shaped probe having an end, a narrow canal with a substantially uniform cross section disposed in the probe, at least one magnifying image-conducting optical system disposed in the canal having a receiving end face, image-illuminating optical systems disposed in the probe in the form of a plurality of optical waveguide strands having transmitting end faces at the end of the probe in immediate vicinity of the receiving end face, the transmitting end faces being grouped in the shape of a fan about the receiving end face for illuminating the measuring site, a UV light source connected to the image-illuminating optical systems for transmitting rays from the transmitting end faces and reflecting the rays off the surface structure in the visible frequency range onto the receiving end face, and means connected to the image-conducting optical system for producing a real image from the rays.
