This page contains SM2 threaded irises. To see the entire family of irises that each part on this page belongs to click on the hyperlined item number in the table to the right.
Our SM2 (2.035"-40) Threaded Irises are threaded internally and externally for compatibility with our SM2 Series Lens Tube and components. This allows for the easy integration of the iris into an optomechanical construction.
Ring actuated Irises are designed for integration into a 60 mm cage assembly, where the movement of a lever actuated iris would be hampered by the cage rods.
