Abstract

A surgical microscope for generating an image of an object region includes an eyepiece and an objective conjointly defining a viewing beam path, an image capturing device and a beam path switching device for out-coupling image information. The switching device is switchable between a first switching state wherein light in the viewing beam path is split into a first component along a first beam path to the eyepiece at an intensity IT1 and a second component along a second beam path to the image capturing device at an intensity IT2 and a second switching state wherein the light in the viewing beam path is deflected into the second beam path to the image capturing device at an intensity IU. The switching device includes a beam splitter movable in and out of the viewing beam path and a deflecting element movable into and out of the viewing beam path.
