Abstract
An adapter for coupling a camera having automatic exposure control to an optical instrument, such as a microscope, for measuring the intensity level of image forming light emanating from the instrument and storing the measurement data, for evaluating the measured light intensity to see if it is in a predetermined range of exposure values, for automatically actuating the camera if the light intensity level is suitable for proper film exposure and thereafter terminating exposure in accordance with the stored data and for inhibiting camera actuation if the measure intensity level is too high or too low for proper exposure.
