Abstract
A video-type stereoscopic microscope is composed of a close-up optical system which emits object light rays from an object as parallel rays, a pair of zoom optical systems which converges the object light rays having passed through different parts of the close-up optical systems and a relay optical system which relays images formed by the respective zoom optical systems to a CCD. Zoom lens barrels which hold the respective zoom optical systems individually are fixed in a zoom housing such that the position thereof can be adjusted in the axial direction. This zoom housing is fixed in a casing of the stereoscopic microscope such that the position thereof can be adjusted in the direction of the optical axis of the close-up optical system.
