ABSTRACT:
A stereomicroscope includes an objective lens for converting light from an object into parallel beams, an imaging lens for forming an image of the object, a prism for erecting the object image, and an eyepiece for observing the object image so that the object image is viewed stereoscopically through the eyepiece, in which the eyepiece is constructed from a single lens system equipped with a variable magnification optical system and an eye lens whose diameter is larger than a viewer's interpupil distance, and optical paths from the object image to the viewer's eyes traverse the positions outside the optical axis of the eyepiece. Thus, the stereomicroscope dispenses with the need for adjustment of the interpupil distance, causes the freedom of the eyepoint to be increased, and allows a viewer to observe the image from any direction whatsoever.
