Irises provide the simplest means of controlling the aperture of an optical system. These iris diaphragms are mounted in housings and calibrated in terms of aperture diameter in millimeters. The aperture may be continuously adjusted and then locked in position by means of the clamp screw. Three sizes cover the majority of beam sizes in common use.
