Abstract: An input coupling module selectively couples a beam path into a first or second stereoscopic component beam in a surgical microscope having an optical interface for guiding a beam path to be coupled-in. The input coupling module has a first beam splitter arranged in the first component beam and a second beam splitter arranged in the second component beam. The input coupling module contains an adjustable optics assembly, which selectively guides a beam path provided at the optical interface for coupling into the first or second component beam to the first beam splitter or the second beam splitter. The adjustable optics assembly includes an optical element displaceable by a linear movement from a first position to a second, position, and vice versa, for switching the beam path. The displaceable optical element is arranged in the beam path to be coupled-in in the first position and/or the second position.
