Beam splitter apparatus comprising at least two beam splitting surfaces having different reflection to transmission ratios

摘要

The present invention relates to a microscope (2), in particular a beam splitter device (1) for a stereoscopic microscope, and further relates to a microscope imaging method, in particular a stereoscopic microscope imaging method. The beam splitter device (1) supports at least two beam splitting surfaces (4, 14). Each of the at least two beam splitting surfaces (4, 14) has a different reflection to transmission ratio. The beam splitter device (1) further has an optical path (3, 3a, 3b). At least one of the at least two beam splitting surfaces (4, 14) is such that the first beam splitting surface (4) of the at least two beam splitting surfaces (4, 14) is positioned in the optical path. The second beam splitting surface (14) of the at least two beam splitting surfaces (4, 14) is moved from the first operating position (15) to the second operating position (16) in the optical path. It is configured to be. With such a configuration, it is possible to change the available light in the branch path (3a, 3b) of the optical path (3) after the beam splitting surface (4, 14). This is particularly convenient if one of the branches (3a, 3b) is directed to an outlet port (8) configured to accommodate a camera. By directing more light to the camera exit port (8), the image quality of the camera can be improved.
