Iris Diaphragms provide continuously variable apertures for applications including setting the numerical aperture of a lens, controlling or measuring the intensity of a diffuse beam, or approximating beam diameters. They may also be used as baffles to reduce spurious reflections and scattered light. Three models offer aperture sizes from 1 mm to 41 mm in overlapping ranges.
Designed for smooth adjustment and the best possible aperture shape, each iris consists of an array of curved, spring-steel leaves whose orientation is determined by the relative position of two rings. A pin handle on the inner ring lets you adjust the aperture without risk of obstructing the beam path.
The miniature ID-0.5 Iris Mounts in the MH-2P Optic Holders for attachment to SP and MSP Posts or Pedestals. ID-1.0 and ID-1.5 Irises mount directly on Optical Posts and Pedestals.
