Iris Diaphragms

Iris diaphragms are continuously variable, adjustable light stops for alignment and filtering purposes. We offer manual iris diaphragms in post mountable, SM-threaded, or cage-system-compatible housings. Our ring-actuated iris diaphragms are ideal for applications with space constraints, where the levers on typical irises might clash with other components. Additionally, our Motorized Iris, which operates using Elliptec® piezo resonant motors, has features for compatibility with our 30 mm and 60 mm cage systems, as well as SM1-threaded components.
