Abstract: Disclosed is an endoscopic system comprising an excitation beam source located in a proximal supply unit, an optical radiation transmission path in an insertion piece, and a fluorescence converter at the distal end. A laser diode that emits in the shortwave visible spectral range is used as an excitation beam source while a glass fiber is used as an optical transmission path. The fluorescence converter is suitable for converting into white light and is embodied as a fluorescent element that is mounted downstream of the light emergence surface of the glass fiber as a separate, interchangeable part. Said endoscopic system is characterized in that the distal end of the glass fiber and the fluorescent element are inserted into a lighting fixture which has a light emergence opening that widens in a funnel-shaped manner.
