Abstract
The subassembly arranged between a zoom system and the ocular telescope of a stereoscopic surgery microscope for eye surgery comprises a prism system, arranged in a casing, for a complete image reversal with a beam displacement and a direction-invariable optical path, it being possible to move the prism system out of the optical path between the zoom system and the ocular telescope for eliminating image reversal.
