Stainless Steel Series Iris Diaphragms
High Performance Motorizable Irises
• Fast, Accurate, Repeatable Motion
• Dual Control Gear and Lever Mechanics
• Removable Pin for OEM Integration
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. Note: Iris Diaphragm Mounts sold
separately. Motor not included.
