Product Family Description

  • Stainless Steel and Brass Construction for Stability
  • Mounted Version Features both an English and Metric Tapped Hole for Easy Post Mounting
  • Ideal for Flow Control Applications

Stainless Steel Series Iris Diaphragms are designed with stainless steel lever pins and leaves within a blackened brass housing; these units will not rust or corrode under unstable environmental conditions. These diaphragms offer exceptionally smooth operation over the approximately 90° lever travel, from maximum to minimum aperture. Mounted versions of these diaphragms feature both a Metric and English tapped hole for easy post mounting. These diaphragms are offered with maximum apertures of 8 – 75mm, and with outer diameters ranging from 14.8 to 100mm. Stainless Steel Series Iris Diaphragms are ideal for dynamic control of beam width and light throughput in optical systems where environmental factors are a concern.

For specific OEM application assistance, please contact our Applications Engineering Department.

Note: Iris Diaphragm Mounts sold separately.
