ABSTRACT:
The invention involves an adapter with peripheral image averaging means for exposure control or attaching an automatic exposure control camera or camera with an exposure meter to a microscope for the purpose of photographing the material on the microscope stage. The adapter uses a separating element which divides the magnified image into the part which completely fills the camera's rectangular film format allowing it to pass to the film without appreciable interference and the remaining part, the peripheral image, which the separating element collects and directs toward the camera's automatic exposure control port where a reflector aims the extracted second part of the magnified image onto a translucent screen in front of the camera's exposure control port.
