ABSTRACT:
A stereoscopic microscope including a light source section, an illumination optical system, and an observation optical system. The illumination optical system has an optical axis and includes a projection optical system. The projection optical system forms an intermediate image and irradiates a light flux from the light source section onto an observation object. The observation optical system includes an objective lens, a pair of left and right zooming optical systems for changing the magnification of the observation optical system, and a pair of left and right eyepiece optical systems. A center position of the light source section is de-centered from the optical axis of the illumination optical system. Also, the illumination optical system includes a reflecting member which has two rounded notches and is inserted into and removed from a space on the object side of the objective optical system in conjunction with a zooming operation.
