PROBLEM TO BE SOLVED: To provide an optical apparatus for medical purposes which approximately aligns the observation area of an operator and the photographing area of a photographic means without making regulation at all when lenses of different sizes are attached or detached or when the mounting direction of the lenses is changed. SOLUTION: The optical apparatus for medical purposes approximately aligns the observation optical axis of a magnifier 10 and the photographic optical axis of a TV camera 12 near the focal position of both and mountably attaches and detaches the TV camera 12 to and from the magnifier 10 at least at two kinds of angles of the observation optical axis of the magnifier 10 and the photographic optical axis of the TV camera 12. |
