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.

Ring-Activated Threaded Iris Diaphragms
Outer Ring Actuates Iris Aperture
This threaded ring-activated iris diaphragm is specifically designed for use in space-constrained areas where the use of a lever is not possible or practical. For instance, in a cage system, the motion of a lever may be blocked by the cage rods. In this case, ring-actuated irises are an excellent solution. The ring actuator turns smoothly and can be locked into position with a setscrew.
