Do your iris diaphragms have mounts for breadboard applications?

We offer a line of Mounted Iris Diaphragms for our most popular irises; 19.8mm, 37mm, 53mm, and 70mm outer diameters. The mounted diaphragms have a ¼-20 mounting hole (#8-32 for the 19.8mm model) and tolerances are held tight to ensure accurate centering. We also sell the mounts separately for our most popular standard irises in the sizes listed above; as well as, for our Zero Aperture and Stainless Steel series of iris diaphragms.
