A surgical microscope employs a pentaprism beam splitter as a branching unit to branch each beam passed through variable power optical systems into a first beam and a second beam, the first beam being horizontally reflected for an eyepiece unit, the second beam being vertically transmitted for an imaging device. The pentaprism alone is capable of simultaneously conducting reflection to provide an erect image and transmission to provide a photographing image, thereby reducing the number of optical parts in a microscope body of the surgical microscope.
