Abstract:
A photometric apparatus for a microscope, the apparatus comprising:a photographing shutter disposed on an optical axis of an observation light from a microscope main body; a mirror disposed closer to the microscope main body than said photographing shutter is to the microscope main body, said mirror being freely shifted onto and away from the optical axis; a rotary member rotatably supported by a rotation axis holding said mirror and parallel to the optical axis; a spring which urges said rotary member to rotate; a stopper which positions said rotary member by coming into contact with said rotary member; a cam which rotates said rotary member by pushing so as to separate said rotary member from said stopper; a motor which rotatably drives said cam; a light-reception element disposed on an optical axis of light reflected by said mirror and performing photometric measurement on the observation light, wherein, in a state in which said rotary member is positioned by said stopper, said mirror is shifted on the optical axis, the observation light is guided to said light-reception element, and photometric measurement is performed, and wherein, in a state in which said rotary member is rotated by said cam to a position separated from said stopper, said mirror is shifted away from the optical axis and the observation light is guided to said shutter.
