This is a 6-pack of the ID-1.5Iris Diaphragm. The ID-1.5 Iris Diaphragm uses 18 leaves to provide a continuously variable aperture 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. The ID-1.5 offers a 2.4 to 41.3 mm aperture range. 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. ID-1.5 Iris Diaphragm mounts directly on Posts and Pedestals.
