16 mm Cage System Iris Diaphragm
For 16 mm Cage Systems
The SP8D Iris in a 16 mm Cage System. The low-profile button-head screw clears the fourth cage rod, allowing the iris to be actuated.
This lever-actuated, continuously variable, cage-system-compatible iris diaphragm is designed to provide smooth operation over many thousands of cycles. This iris is mounted in an ultra-thin, cage-system-compatible plate that engages three cage rods with locking screws that accept a 0.05" (1.3 mm) hex key. The steel leaves within the iris are actuated by a button head lever that clears the fourth cage rod, as shown in the picture above, allowing for operation within the cage system. This iris has a maximum aperture of Ø8.0 mm and is permanently installed in the cage plate.
