16mm C-Mount lens for up to 1.2" sensors such as IMX541

The CIL583 is a 16mm C-mount lens for 1.2" sensors up to 25MP at 2.74μm pixel pitch, including the Sony IMX541. It gives you a 62.5° field of view across a 19.4mm image circle, so the lens covers a broad working area without stepping down to a shorter focal length. The adjustable iris runs from F/2.4 wide open to approximately F/16–18, which lets you trade throughput for depth of field without changing lenses.

Distortion is -1.7% from rectilinear. That number is low enough for dimensional measurement and many metrology setups, especially if the system values field coverage along with accuracy. The minimum object distance is 125mm, so the lens can work fairly close for a large-format optic but still has room for broader inspection stations.

The lens uses all-glass optics and weighs 175g. That weight is higher than a small C-mount lens, but the trade buys you large-format coverage and a more stable mechanical package on fixed factory equipment. The M40.5x0.5 filter thread also lets you add standard 40.5mm ND or polarizing filters when glare from reflective parts becomes the real problem.

The standard C-mount 1"-32 TPI thread fits Basler ace2, FLIR Oryx, Allied Vision Alvium, Lucid Triton, and other industrial cameras with C-mount interfaces. You can use field of view calculator to confirm working area before you lock in the station design.

Commonlands ships in-stock parts same day from San Diego for orders before 12 PM PST. You can contact the optical engineering team if you need help comparing the CIL583 and CIL553 for a 25MP system.
