50mm C-Mount lens for up to 20MP 1.1" Sensors

CIL546 is a 50mm C-mount lens for 1.1" sensors at 20MP and above with 2.74µm pixel pitch compatibility. It pairs well with the IMX540 and similar sensors. The 17.6mm image circle gives a 20° field of view, so you get tight framing at longer working distances starting from 250mm.

The aperture adjusts from F/2.8 to F/16, which lets you choose between more light and more depth of field. Distortion is 0.07%, which is effectively zero for dimensional measurement, metrology, and gauging. Most systems will not need software correction at that level. The all-glass construction also holds focus better on a factory floor when temperature moves around.

The lens weighs 127g and uses an M35.5x0.5 filter thread for bandpass, polarization, or neutral density filters. The full 17.6mm image circle covers the 1.1" format edge to edge, so you are using the whole sensor instead of cropping it.

Commonlands ships this lens as CIL546-F2.8-CMANIR without filter. It works well with 1.1" area scan cameras from Lucid, FLIR, Basler, and Ximea.

The lens ships same day from San Diego for orders before 12 PM PST. You can contact engineering@commonlands.com for volume pricing or application support on long working distance inspection setups.
