The threaded ring-actuated iris diaphragms are designed for use with our LT series lens tubes or other components with SM1 or SM2 threads. They are easily operated by rotating the outermost ring for smooth adjustment of the aperture size, and the ring can be locked in place once desired aperture size is achieved.

The threaded ring-actuated iris diaphragms feature an external SM thread on one end and internal SM thread on the other end, allowing easy installation into our lens tube system or OpticsCage+™ cage system with minimal alignment required.
The threaded iris diaphragms are offered in two sizes for 1 and 2 in. components. They are low profile with no lever sticking up that could lead to unintended changes. A setscew on the side of housing can lock the iris in place once designed opening is achieved.
The 1.0 in. iris diaphragm is also offered in a graduated version. It allows the user to determine the size of the adjusted aperture even when the iris is enclosed by lens tubes.
