Abstract
An endoscope includes a hollow handle housing and an insertion tube including a tip part at the distal end of the endoscope. The tip part includes an illumination arrangement with an elongated single-piece light guide having a proximal light guide end and at least one distal light guide end, wherein the proximal light guide end is adapted for receiving at least one light fiber. The at least one distal light guide end has an end surface adapted for emitting the light from a light source. The cross-section of the proximal light guide end differs from the cross-section of the at least another part of the light guide.
