Abstract
A stereoscopic microscope is disclosed that includes an objective lens which substantially collimates light from an object of interest, left and right afocal zooming systems, left and right afocal relay systems, and an ocular tube optical system which forms magnified images of the object. The optical axis of the objective lens is substantially normal to a plane that includes the optical axes of the left and right afocal zooming systems, a beam splitter is arranged in each optical path between the left and right afocal zooming systems and said ocular tube optical system, and in each optical path between the left and right afocal zooming systems and the ocular tube optical system, there is at least one region between the beam splitter and the ocular tube optical system where the optical axes of light fluxes from an observation object point intersect. Preferably, there are additional regions of intersecting light.
