Our standard series iris diaphragms have been specifically designed for OEM integration and general laboratory use. All offer exceptionally smooth operation over the lever travel, from maximum to minimum aperture (approximately 90°). Lever actuators are available in two styles: stainless steel “pin” or plastic “tab.” All standard series diaphragms have blued spring steel leave construction and black housing finish.
Incorporated into standard optical systems, iris diaphragms can provide control of system f/# (f/# = focal length/effective diameter), field stop diameter, and overall energy throughput. It should be noted, however, that the location of the iris is critical to how it will affect the system. For specific OEM application assistance, please contact our Applications Engineering Department.
Note: Iris Diaphragm Mounts sold separately.
