ABSTRACT:
A stereoscopic microscope is provided with an objective, a pair of relay lens systems having optic axes parallel to each other, a pair of optic axis deflecting prisms for bending the optic axes of the relay lens systems to thereby form a predetermined angle of depression, the prisms being rotatively displaced with respect to the optic axes of the relay lens systems to form a predetermined angle of convergence, and an auxiliary prism cemented to a predetermined reflecting surface of at least one of the pair of optic axis deflecting prisms for forming an optical path different from an optical path leading to a finder system.
