TECHSPEC® High Performance Motorizable Irises are designed for integration into custom applications and for use in a lab environment. These irises include two methods for controlling the aperture size: one by a standard pin which enables standard angular deviation and the other that duplicates the movement of the pin by replicating the teeth of a spur gear on the inner housing of the iris. This feature allows for custom motion control in conjunction with a compatible spur gear. TECHSPEC® High Performance Motorizable Irises maintain fast, accurate, and repeatable movement to any location through the iris’s range of motion. The 7mm, 12mm, 22mm, 28mm, and 38mm Max Aperture configurations are also available with Anti-Reflection (AR) Leaves.
