C, S, and T-Mount Iris Diaphragm Mounts

Variable Apertures for C, S, and T-Mount Systems
Male and Female Thread at Opposite Ends for Easy Integration
Adjusted via Rotating Ring or Lever for Precision Control

TECHSPEC® C, S, and T-Mount Iris Diaphragm Mounts feature iris diaphragms that allow for precision control over the internal aperture within a system. Using male and female threads, these mounts can be placed anywhere within a C, S, or T-Mount system. The apertures can be adjusted via a rotating ring for the C-Mount version, with a 4mm lever for the S-Mount version and with a 5mm lever for the T-Mount version. TECHSPEC C, S, and T-Mount Iris Diaphragm Mounts add 12mm, 12mm, and 18mm to the system length, respectively. These mounts are ideal for providing control over the f/#, field stop diameter, and overall energy throughput of a C, S, or T-Mount system.

NOTE: The iris planes sit approximately 15mm, 8mm, and 12mm from the female ends of the TECHSPEC C, S, and T-Mount Iris Diaphragm Mounts, respectively.
