Abstract
The invention is directed to a stereomicroscope having a main objective of variable focal intercept. An optical element is provided in each of the two stereoscopic component beam paths to provide a parallel displacement of the particular beam path. A coupling between each displacement of the two stereoscopic beam paths and the actual adjustment of the focal intercept of the main objective is also provided in such a manner that a preselectable constant stereo angle results even when there is a variation of the focal intercept of the main objective. In this way, a physiologically constant viewing impression results for the viewer.
