Endoscopic system with fibre-pumped fluorescence illumination

摘要

The system (1) has an excitation radiation source (5) arranged in a proximal supply unit (4), an optical radiation transmission path i.e. glass fiber (8), in an insertion piece (3), and a fluorescence converter at a distal end of the path. A laser diode (6) emits in a shortwave visible spectral range, which is used as the excitation radiation source. The fluorescence converter is designed as a fluorescent body that is mounted downstream of a light emergence surface of the path as a separate, interchangeable part. The distal end and the body are inserted into a lighting fixture (10).
