SURGICAL MICROSCOPE HAVING OPTICAL INTERFACES

摘要

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.

1. In an optical instrument defining first and second stereoscopic component beams, an incoupling module for selectively coupling a beam path into said first component beam or into said second component beam is provided at an optical interface, said incoupling module comprising:
a first beam splitter arranged in said first stereoscopic component beam path; a second beam splitter arranged in said second stereoscopic component beam path; an adjustable optics assembly configured to selectively direct the beam path to the first beam splitter or the second beam splitter; the adjustable optics assembly including a first mirror element displaceable by linear movement from a first position to a second position and vice versa relative to the optical interface; said mirror element being arranged in the beam path in the first position thereof; a second mirror element configured to direct said beam path to said first beam splitter for coupling into said first stereoscopic component beam; said first mirror element, in said first position, being configured to direct the beam path to said second mirror element, and, in the second position, clearing said beam path to the second beam splitter for coupling into the second stereoscopic component beam; and, said beam path defining an optical axis which is an axis of symmetry passing through said second beam splitter.
