Ø 23 mm.

The iris shutter is ideal for pistol or rifle shooters, who shoot with open adjustment. This replaces the diopter and improves the focus (depth of field). It is put on the lens-holder from behind to avoid disturbing reflexes in the lens. It can be used for right or left aiming shooters. Iris shutters are available for big and small lens holders.
