ABSTRACT:
A stereo microscope arrangement includes an objective used in common, at least a first and a second pair of stereoscopic observation beam paths and an illuminating unit with at least one deflecting element that deflects illuminating light in the direction of the object plane. The illuminating unit is arranged so that it can be mounted in at least two different positions relative to the stereoscopic beam paths. Accordingly, optimized illuminating conditions can be selectively placed at the disposal of the main observer or the co-observer.
