Patent ID: 7894130

Claim:
A stereomicroscope comprising: a first main beam path and a second main beam path whose spacing from each other defines a stereo base; a microscope axis proceeding through the center of the stereo base parallel to the first and second main beam paths; and an optical beam splitter device for generating an assistant's beam path and a documentation beam path, wherein the beam splitter device is adjustable to a first position in which the assistant's beam path is outcoupled from the first main beam path and the documentation beam path is outcoupled from the second main beam path, and to a second position in which the assistant's beam path is outcoupled from the second main beam path and the documentation beam path is outcoupled from the first main beam path; the assistant's beam path is outcoupled in a first direction when the beam splitter device is in the first position and is outcoupled in a second direction 180 degrees opposite the first direction when the beam splitter device is in the second position; and the documentation beam path is outcoupled in a third direction perpendicular to the first and second directions.
