Abstract:
A stereoscopic microscope comprising:a common close-up optical system that faces an object, said close-up optical system having a single optical axis; a pair of zoom optical systems that take object light rays passing through the different regions of said close-up optical system, respectively, to form a pair of primary images, the optical axes of said zoom optical systems being parallel to the optical axis of said close-up optical system; a pair of field stops that are arranged at the positions of said primary images; a pair of relay optical systems that relay said primary images to form a pair of secondary images; an inter-axis distance reducing element that brings the object light rays from said relay optical systems close to each other; an image taking device that captures said secondary images formed on an image taking surface thereof; and an illuminating optical system that guides illumination light emitted from a light source to illuminate said object.
