Projection optics for projector, has interference filter integrated into housing of optics, and filter clamping mechanism comprising retaining rail that is provided for retaining motor e.g. stepper motor
The optics (10) has an interference filter (9) integrated into a housing (7) of the optics, and a filter clamping mechanism comprising a retaining rail. The retaining rail is provided for retaining a motor e.g. stepper motor (2), that is provided for controlling the clamping mechanism. A rotating lever is arranged at the motor, and an outer moving rod (4) is coupled with the lever. A retainer for the filter is coupled with an inner rotating rod that is attached to another small rotating lever.
