ABSTRACT:
In order to better cover the operating field with a stereoscopic operating microscope in connection with a television camera, the operating microscope is provided with a beam divider, whose two beam divider elements (2, 2') inserted into the parallel optical path of the two optical viewing paths (1,1') are disposed in such a way relative to each other that the ray bundles (4,4') deflected by the beam divider elements (2,2') intersect at least once in one plane and are reflected once on reflecting elements (5,5') disposed vertically to this plane, before the ray bundles (4,4') impinge upon image-recording chips (7,7') of camera systems.
