摘要 |
A photometric apparatus for a microscope comprises a light-reception element having a plurality of concentrically arranged photometric measurement areas, the light-reception element receiving observation light from the microscope and measuring a brightness of an observation image of the observation light, a calculation circuit for calculating an exposure time necessary for photographing the observation image, on the basis of a photometric measurement value obtained from at least one of the photometric measurement areas of the light-reception element, and a control circuit for performing an exposure operation on the basis of the exposure time calculated by the calculation circuit.
