Iris Diaphragms
Iris diaphragms are continuously variable field or aperture stops for the use in optical experiments or apparatus.
The diaphragm leaves are made of spring steel and can move smoothly within the cylindrical mount made of brass. The diaphragm opening is adjusted by means of a radial pin actuator with a small knob.
Holders are available for posts mounting in optical setups. The iris diaphragm is inserted into the holder with detached actuator pin. Then the actuator pin is refitted into the iris diaphragm through the operation slit of the holder. An adapter is supplied for mounting posts with M8 thread.
