Abstract
An iris diaphragm comprises a stationary circular base having a pair of opposite sides and pivot pins at only one of the sides, a plurality of opaque blades positioned adjacent the side of the circular base that has the pivot pins to define an aperture between the blades, and having pivot holes that contain the pivot pins to permit the aperture to be changed in size by pivoting the blades about the pivot pins, a rotatable ring positioned adjacent the side of the circular base without the pivot pins, and a plurality of interconnections between the ring and respective ones of the blades to make rotation of the ring relative to the circular base pivot the blades about the pivot pins.
