Abstract (en)
[origin: WO2008058612A1] Disclosed is an endoscopic system (1) comprising a excitation beam source (5) located in a proximal supply unit (4), an optical radiation transmission path in an insertion piece (3), and a fluorescence converter at the distal end. A laser diode (6) that emits in the shortwave visible spectral range is used as an excitation beam source (5) while a glass fiber (8) is used as an optical transmission path. The fluorescence converter is suitable for converting into white light and is embodied as a fluorescent element (12, 22) that is mounted downstream of the light emergence surface of the glass fiber (8) as a separate, interchangeable part. Said endoscopic system (1) is characterized in that the distal end of the glass fiber (8) and the fluorescent element (12, 22) are inserted into a lighting fixture (10) which has a light emergence opening (13) that widens in a funnel-shaped manner. Alternatively, the fluorescent element (12, 22) is disposed in a replaceable head (16) which can be coupled to the insertion piece (3) and encompasses additional optical and heat-dissipating components in order to generate an illumination beam and/or measurement beam.
