12mm High Resolution C-Mount lens \| 25MP sensors w/2.5um pixels such as GMAX0505, TRI204S, TRI245S

CIL542 is a 12mm C-mount lens for 1.1" sensors running 25MP at 2.5µm pixel pitch. It covers the GMAX0505, TRI204S, and TRI245S with a 17.6mm image circle and 72° field of view. The aperture adjusts from F/2.8 to F/16, so you can trade light for depth of field when a line runs around 100mm working distance.

Distortion is -0.6% from rectilinear at minimum object distance, which is low enough for dimensional measurement and gauging without software correction in many setups. The all-glass optical design stays more stable through temperature swings than hybrid alternatives. The IR-corrected optics also stay sharp in visible and near-IR without a refocus step.

The lens weighs 255g and uses an M46x0.75 filter thread. That size tells you this is a full industrial C-mount lens, not a compact board-camera optic. The finite/infinite conjugate optimization keeps the field flat from 130mm working distance out to infinity instead of letting field curvature soften the corners.

Commonlands ships one variant: CIL542-F2.8-CMANIR without filter. The M46x0.75 thread accepts standard machine vision filters for bandpass or polarization. The lens works with 1.1" format area scan cameras from Lucid, FLIR, Basler, or Ximea.
