Beam splitter device with at least two beam splitting surfaces having different reflection to transmission ratios

摘要

The invention relates to a beam splitter device (1) for a microscope (2), in particular a stereoscopic microscope and to a microscope imaging method, in particular a stereoscopic microscope imaging method. The beam splitter device (1) supports at least two beamsplitting surfaces (4, 14). Each of the at least two beamsplitting surfaces (4, 14) has a different reflection-to-transmission ratio. The beam splitter device (1) further comprises an optical path (3, 3a, 3b). At least one of the at least two beamsplitting surfaces (4, 14) are configured to be moved from a first operation position (15), in which a first (4) of the at least two beamsplitting surfaces (4, 14) is located in the optical path, to a second operation position (16), in which a second (14) of the at least two beamsplitting surfaces (4, 14) is located in the optical path. With this configuration, it is possible to change the available light in the branches (3a, 3b) of the optical path (3) after the beamsplitting surface (4, 14). This is particularly useful if one of the branches (3a, 3b) is directed to an exit port (8) which is configured to receive a camera. By directing more light to the camera exit port (8), the image quality of the camera can be improved.
