ABSTRACT:
An endoscope has an objective arranged at its distal end, the image of which a relay-lens system conveys to the proximal end of the endoscope a light guide at least partially surrounds the relay-lens system and the objective, and conveys illumination light of an illumination light source from a light-entry connection to the distal end.
The light guide is provided with a hollow-cylinder made of a transparent and optically clear material which surrounds the objective and the relay-lens system. The light from the illumination light source can be coupled into the circular front face of the hollow cylinder.
