Iris Diaphragms

The CP-IRS iris diaphragm is a convenient tool for aligning cage optics. These lever-actuated, continuously variable, cage-compatible iris diaphragms operate smoothly over thousands of cycles. These iris diaphragms are housed in ultra-thin cage-system compatible boards. The steel blades included in the iris are driven by a button head lever that replaces the fourth cage lever. Can be used to align visible beams. The CPPT-30 provides Ø1~20 mm through holes.
