The relay lens system includes by an image-forming lens for forming an image of an object, and a relay lens portion for transmitting the image formed by the image-forming lens, and has one optical axis. The pupil dividing stop unit divides an object image transmitted by the relay lens system to obtain a plurality of object images which are to be subjected to stereoscopic observation. The camera head receives the plurality of object images that are formed through division by the pupil dividing stop unit and performs stereoscopic observation. The relay lens system and the pupil dividing stop unit constitute an integral optical, system yet are axially movable relative to one another. The main body of the optical lens system side and the camera head can be attached with and detached from each other.
