Abstract: A method for operating an automatic exposure control of a selfcontained camera coupled to an image-forming optical instrument without detracting from the brightness of the useful image to be recorded on the camera''s film format and an adaptor for carrying out the method. The adaptor includes optical means that extracts a portion of the light emerging from the optical instrument, at a separation between the instrument and the camera, otherwise destined to form an unrecorded portion of the image.

Abstract: The invention is an optical element, one version of which is useful for operating an automatic exposure control of a selfcontained camera coupled to a microscope without detracting from the brightness of the magnified image to be recorded on the camera''s film format. The article includes three reflecting surfaces arranged to extract a small part of the light emerging from the microscope''s eyepiece and direct it into the photodetector of the automatic exposure control. A lens refracts the light, after the third reflection, to improve the distribution of the light onto the camera''s photodetector. The article is suitable for manufacture as a homogeneous molding of transparent plastic.
