Abstract

An endoscope pipe with a central, elongated observation window on the distal end, whereby several light outlet openings for fiberoptic end surfaces are positioned close to the observation window for illuminating the angle area observed through the observation window and the light outlet openings are positioned asymmetrically in relation to the longitudinal extension of the observation window and/or the fiberoptic end surfaces are held in the light outlet openings in such a way that light is beamed from the fiberoptic end surfaces into the angle area in various directions.
