IR Corrected 8mm Lens for up to 4MP 1/2.5" Sensors such as OX05B1S

The CIL544 is a 25mm C-mount lens for 20MP and above on 1.1" sensors with 2.74μm pixel pitch. It matches sensors like the GMAX0505, Lucid Vision TRI204S, and TRI245S. The iris adjusts continuously from F/1.8 wide open to fully closed, so you can tune exposure and depth of field around the actual station instead of around the catalog spec.

The CIL544 measures -1% from rectilinear at minimum object distance. That is low enough for metrology and dimensional inspection in many systems without the extra work of correction. The 39.1° field of view across the 17.6mm image circle puts the lens in the mid-telephoto range for factory automation and quality control. You can verify coverage at field of view calculator

The lens uses an all-glass construction and weighs 88g, so it stays balanced on standard C-mount machine vision cameras. The front takes M30.5x0.5 filters for ND, bandpass, or polarizing options. Focus runs from 130mm to infinity, and the design is optimized for both finite and infinite conjugate use. That flexibility is still unusual in this class.

One variant ships as CIL544-F1.8-CMANIR without a filter in C-Mount A configuration. The fast F/1.8 aperture matters on high-speed lines where shutter time gets tight and light is never as generous as the mechanical designer promised. You can estimate your depth of field

All in-stock units ship the same day from San Diego when you order before 12 PM PST. Every lens is 100% MTF tested at our ISO 9001:2015 facility. Contact engineering@commonlands.com if you need volume pricing or application support on high-resolution C-mount systems.
