CP20S Iris in a Cage System with
Thorlabs’ Cage System Irises are designed for use within a cage system. The button head lever on these irises clears the fourth cage rod, allowing for aperture adjustments within the cage system.
These lever-actuated, continuously variable, cage-system-compatible iris diaphragms are designed to provide smooth operation over many thousands of cycles. These irises are mounted in ultra-thin, cage-system-compatible plates that engage three cage rods with a flexure mechanism that tightens using a 5/64" (2.0 mm) hex. The steel leaves that comprise the iris are actuated by a button head lever that clears the fourth cage rod, as shown in the picture to the right, allowing for operation within a cage system. These large-aperture irises provide the maximum aperture available for use within a cage system and are permanently installed in the cage plates.
In addition to the cage system irises sold on this page, our SM-Threaded Ring-Actuated Irises can also be utilized in a cage system with the use of an SM-threaded cage plate. However, the cage system irises featured on this page offer larger apertures and thinner profiles than the ring-actuated irises. For non-cage system use, we also offer Post-Mountable Irises, SM-Threaded Lever-Actuated Irises, and Unmounted Irises with no mounting holes.
