PURPOSE:To provide a stereomicroscope capable of reducing the drop of image brightness, the generation of shading and the generation of abnormality in a stereoscopic sense even when a part of a mirror body is moved so as to easily observe an object. CONSTITUTION:A pair of right and left light flux moving members 18 or one light flux moving member 18 is arranged in the right and left light flux of the stereomicroscope having a pair of right and left objective optical systems 19 and a pair of right and left eyepiece optical systems 20. The member 18 is moved synchronously with the movement of the optical members arranged on the object side or image side observed from the member 18. The member 18 can change the position or angle of light flux in accordance with its movement and an image rotor prism having the odd number of reflections, an image rotor mirror, a mirror for deflecting light flux, a wedge type prism capable of changing a distance between two parallel plates to be rotated, etc., are adopted for the member 18. |
