Description: 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 aligning optics to a laser beam. They may also be used as baffles to reduce spurious reflections and scattered light. Three sizes span 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.
Iris diaphragms mount directly to a variety of Newport components - SP Posts, MSP Posts, MH-2P, and Riser Blocks.
