Apparatus for homogenizing the non-homogeneous light distribution of a laser beam |
摘要 |
An apparatus for precise, homogeneous and sharp-edged irradiation of a large area with the light of a laser beam (5), which can be used especially for large-area photodynamic therapy, is provided with a multimode fibre (10), which is illuminated by the laser beam by way of a microscope objective (4) and has a length of approximately 5 meters, and the end face (13) of which is imaged onto an irradiated area (7) of a working surface (6) by means of a microscope (17).
