Abstract
A photographing apparatus for microscopes, in order to make it possible to obtain a photograph of a proper exposure always irrespective of the size of a sample image, comprising an indicator arranged in a position substantially conjugate with an image surface of the photographing apparatus, a first light source for illuminating the indicator, an output generating means for determining an exposure time in photographing of a sample image and an adjusting means capable of proportionally adjusting the brightness of the first light source and an output to be issued from the output generating means, an output to be issued from the output generating means being determined so as to make it possible to photograph the sample image with a proper exposure by operating the first adjusting means to make the brightness of the indicator coincide with the brightness of the sample image formed on the indicator. This apparatus can be detachably mounted on the body of a conventional automatic exposure photographing apparatus for microscopes, is simple in the structure and can be manufactured at a low cost.
