ABSTRACT:
A stereoscopic microscope comprising an objective lens system and a variable magnification optical system which are disposed coaxially with each other in addition to an eyepiece optical system, and configured so as to permit stereoscopic observation of an image of an object by leading, to right and left eyes of an observer by way of the eyepiece optical system, rays having passed through portions apart from optical axes of the objective lens system and the variable magnification optical system. This stereoscopic microscope has a length as measured from the observer's eyes to the object to be observed which is shortened by disposing at least two reflecting members in the variable magnification optical system for bending an optical path in the variable magnification optical system.
