Abstract
A stereomicroscope (20) has first and second main beam paths (21, 22) whose spacing defines a stereo base (23), a microscope axis (24) proceeding through the center of the stereo base (23) parallel to the main beam paths; and an optical beam splitter device (30) for generating an assistant's beam path (31) and a documentation beam path (32), the assistant's beam path being outcoupled from the first main beam path in a first position of the beam splitter device, and from the second main beam path in a second position, and the documentation beam path being outcoupled from the other main beam path; and the direction of the assistant's beam path in the first position being rotated 180° relative to the assistant's beam path in the second position; and the outcoupled documentation beam path extending, in both positions of the beam splitter device, perpendicular to the outcoupled assistant's beam path.
