Abstract
An iris diaphragm device for a microscope includes an iris diaphragm having a stationary mount ring, a rotatable adjusting ring, and a plurality of blades. The plurality of blades form a diaphragm opening, which is steplessly adjustable, by rotation of the adjusting ring, between a maximum and a minimum opening size. A coupling linkage is connected to the adjusting ring and includes two levers. An actuation element drives the coupling linkage. A closure element is arranged on one of the levers in a way such that after a predefined size of the diaphragm opening has been established, a further actuation of the actuation element causes the closure element to pivot and cover the diaphragm opening.
