Abstract
A stereo microscope has a stereo pair of photographs illuminated by a condenser lens illuminating system. A pair of primary magnifying objective lenses focus a magnified image of the stereo pair upon a pair of small diffuse screens. A pair of large aperture objective lenses focus the images on the small diffuse screens in superimposed relationship upon the plane of a large field lens that focuses respective ones of the superimposed further magnified images upon a pair of exit pupils through which an observer looks. The primary magnifying objective lens, the small diffuse screen and the exit pupils are aligned along respective left and right optical axes. The large aperture objective lenses are displaced slightly toward each other from these optical axes. The field lens is centered about an axis midway between the left and right axes.
