The invention concerns a coupling-in module (128) for selectively coupling a beam path (156) into a first or second stereoscopic partial beam path (118, 120) in an operating microscope, with an optical interface (144) for supplying a beam path (156) to be coupled in. The coupling-in module (128) has a first beam splitter (136), which can be disposed in the first stereoscopic partial beam path (118), and a second beam splitter (138), which can be disposed in the second stereoscopic partial beam path (120). The coupling-in module (128) contains an adjustable optics assembly (160) which selectively feeds a beam path (156), prepared at the optical interface (144), to the first beam splitter (136) or the second beam splitter (138) for coupling into the first or second stereoscopic partial beam path (118, 120). According to the invention, in order to switch the beam path, the adjustable optics assembly (160) comprises at least one optical element (164) which can be displaced in a linearly movable manner from a first position into a second position and vice versa and which is disposed in the first position and/or in the second position in the beam path (156) to be coupled in. The invention also concerns a decoupling module (134) for selectively decoupling a beam path out of a first or second stereoscopic partial beam path (118, 120) in an operating microscope which comprises an optical interface (146) for preparing the beam path, a first beam splitter (140), which can be disposed in the first partial beam path (118), and a second beam splitter (142), which can be disposed in the second partial beam path. The decoupling module (134) also contains an adjustable optics assembly (166), which selectively feeds a beam path (158) decoupled from the first or the second stereoscopic partial beam path to the optical interface (146). According to the invention, in order to switch the beam path (158), the adjustable optics assembly (166) comprises at least one optical element (168) which can be displaced in a linearly movable manner from a first position into a second position and is disposed in the first position and/or in the second position in the decoupled beam path (158). |
