Abstract
A stereoscopic microscope includes a binocular eyepiece arrangement, a binocular magnification changer, and a monocular lens arrangement. A reversal lens system can be inserted into beam paths in front of or behind the magnification changer, whereby it exchanges the two beam paths against one another and at the same time causes an image reversal. Thus, the microscope enables quick and simple changing between two focusings of the microscope without limiting the operation of the magnification changer. A supplementary lens can be inserted on the input side of the lens arrangement into the beam paths and an optic system can be inserted into the beam path between the supplementary lens and the eye for wide-angle viewing of the retina. The supplementary lens is a convex lens, the focal length of which is chosen in such a manner that the retina can be viewed with the microscope through the inserted supplementary lens and the optic system, while the lens arrangement of the microscope is focused on the cornea.
