Abstract:
A stereoscopic microscope, comprising:a close-up optical system that emits object light rays from a predetermined object as parallel rays;a pair of image-forming optical systems that converges said object light rays which are passed through different parts of the close-up optical systems to form respective real images of said object;a pair of image-forming lens barrels that holds said image-forming optical systems, respectively;a lens barrel housing that holds each of said image-forming lens barrels such that positions of said image-forming lens barrels are adjustable, while keeping a condition that optical axes of said image-forming optical systems are in parallel with each other, in a direction of said optical axes; anda casing holding said close-up optical system, and also for holding said lens barrel housing such that a position of said lens barrel housing is adjustable, while keeping a condition that each of the optical axes of said image-forming optical systems is in parallel with an optical axis of said close-up optical system, in a direction of said optical axis.
