ABSTRACT:
A photographing unit for a microscope has a photometric detector to measure brightness of light from a sample and includes a changing member which changes a brightness of light toward an observation system and a control unit which controls the light based on a detection output of the photometric detector. In addition, the changing member can be controlled based on the presence of an observer. A shielding member can be provided that automatically shields an optical path of the observation system. An illumination system for an index on a reticle can be provided so that the illumination of the reticle can be performed or extinguished at desired times. Additionally, the color of light with which the index is illuminated may be made distinguishable from the color of light from a sample, and the contrast of the index to the sample can be controlled.
