Abstract
The present application is directed to an optical scanning system for medical applications, preferably in ophthalmology, which can be used for a large range of diagnostic and therapeutic applications. The optical scanning system comprises at least one controllable reflector which has an actuator and which is arranged in a first imaging beam path for deflecting at least one therapy beam and/or diagnosis beam over a work field in a scanning manner, a second imaging beam path for a fixation beam which is imaged on the work field in a spatially fixed manner with respect to the optical axis of the system, and a central control unit. The moving reflector is used to unify the two imaging beam paths and has dichroic characteristics so that it is transmissive for the fixation beam and reflective for the therapy beam and/or diagnosis beam(s). The second radiation source which serves to generate the fixation beam is controlled so as to be synchronized to the position of the moving reflector.
