Abstract
A photographing apparatus for microscopes is constructed so that a simultaneous observation is made by overlapping an image of a sample formed by transmitted illumination with that formed by reflected fluorescence, in which signals for designating the simultaneous observation at once cause a second shutter for the transmitted illumination to be closed and a first shutter for the reflected fluorescence to be opened, the brightness of the sample image formed by the reflected fluorescence is measured by a light-detecting element disposed in an optical path for observation, and after a light-adjusting member for the transmitted illumination is controlled so that, based on data outputted from a memory device corresponding to a measured value, the brightness of the sample image by the transmitted illumination in the simultaneous observation is balanced with that of the sample image by the reflected fluorescence, the second shutter is opened. Thus, this photographing apparatus has advantages that whenever the microscopy is switched, an operator can dispense with the need for a fine adjustment of the amount of transmitted illumination light, with the resultant ease of operation, the balance adjustment of brightness in switching is made in a short time, and the bleaching of fluorescence of the sample can be suppressed.
