Abstract
A stereomicroscope includes an objective optical system, a variable magnification optical system, and a plurality of imaging optical systems, in which the plurality of imaging optical systems can be moved in a plane perpendicular to the optical axis of the variable magnification optical system. Thus, the stereomicroscope has the advantage that where one of two observers wishes to observe a brighter image, the amount of light can be adjusted, without replacement of a light source, by moving the imaging optical systems.
