Patent ID: 7538939

Claim:
A stereomicroscope comprising: a binocular tube ( 1 ), a microscope body ( 4 ) for passing two stereoscopic observation beam paths ( 3 a , 3 b ), the microscope body ( 4 ) comprising an incident light illumination system or connection therefor and an illumination beam path ( 34 ) separate from the observation beam paths such that when a stereo lens ( 6 ) is selected the illumination beam path passes through the lens ( 6 ), a microscope holder ( 14 ) that is connected to a displaceable focus-adjusting mechanism ( 9 ), the focus-adjusting mechanism ( 9 ) in turn being fastened to a stand ( 13 ), a beam splitter ( 2 a ) used to combine the two stereoscopic observation beam paths ( 3 a , 3 b ) into a common beam path ( 3 c ), wherein the axes of the two observation beam paths ( 3 a , 3 b ) entering into the binocular beam splitter ( 2 a ) and the axis of the beam path ( 3 c ) emerging from the binocular beam splitter ( 2 a ) are parallel to each other, and the axis of the emerging beam path ( 3 c ) is disposed at displacement (Vs) from a symmetry axis of the two entering observation beam paths ( 3 a , 3 b ), a system for coupling an illumination beam path ( 34 ) into the beam path ( 3 c ) emerging from the binocular beam splitter ( 2 a ), a carrier ( 12 ) bearing the microscope body ( 4 ) and being displaceable obliquely relative to a displacement direction of the focus-adjusting mechanism ( 9 ) to compensate for said displacement (Vs), a switching device ( 5 ) held on said holder ( 14 ) and provided with mounts for at least one stereo lens ( 6 ) and at least one compound lens ( 7 ), wherein by actuating the switching device ( 5 ) each of the lenses ( 6 , 7 ) can selectively be brought over an object ( 8 ) and both the stereo lens ( 6 ) and the compound lens ( 7 ) can be placed over the object ( 8 ) parfocally and parcentrically, a gear ( 10 ) which, depending on the position of the switching device ( 5 ), automatically brings about the displacement of the carrier ( 12 ) to compensate for displacement (Vs), wherein the binocular beam splitter ( 2 a ) is disposed between the carrier ( 12 ) and the compound lens ( 7 ).
