Frequently asked questions

What sensors work with the CIL042 no-distortion 4mm M12 lens?

The CIL042 supports 1/1.7 inch and 1/1.6 inch sensors including the Sony IMX678, Sony IMX334, ON Semi AR0822, and Sony IMX226. The 8.8mm designed image circle (9.8mm max) covers these formats with margin.

How much distortion does the CIL042 have compared to other 4mm M12 lenses?

The CIL042 measures -0.7% TV distortion at 4:3 across the 9.3mm image circle. Most competing 4mm M12 lenses run 3-5% distortion at similar fields of view. This low figure means you can skip software correction in most machine vision pipelines.

What aperture options are available for the CIL042?

Three fixed aperture options ship from stock: F/1.9 for maximum light gathering, F/2.6 for a balance of brightness and depth of field, and F/4.0 for maximum depth of field in fixed-focus setups. Use our depth of field calculator at https://commonlands.com/pages/camera-depth-of-field-calculator to compare.

Is the CIL042 compatible with FLIR Blackfly S cameras?

Yes. The CIL042 is mechanically compatible with FLIR Blackfly S board-level cameras using standard M12x0.5 mounts. It also works with Allied Vision Alvium, iDS uEye LE, The Imaging Source M12, and Basler Dart S-Mount cameras.

Does the CIL042 4mm M12 lens ship same day from the US?

All in-stock CIL042 variants ship same day from San Diego, California for orders placed before 12 PM PST. Currently over 400 units across all variants are stocked in the US.

What is the image circle of the CIL042 and does it cover 1/1.6 inch sensors?

The CIL042 image circle is 8.8mm as designed with a 9.8mm maximum. This covers 1/1.7 inch sensors fully and extends to 1/1.6 inch format sensors like the AR0822 and IMX226. Calculate your field of view at https://commonlands.com/pages/camera-field-of-view-calculator.

The CIL042 is a 4.2mm M12 lens designed for 1/1.7" sensors like the IMX678, IMX334, and AR0822. At F/1.9 with only -0.7% TV distortion across the 9.3mm image circle, this is one of the cleanest wide-angle M12 options available for embedded vision. Resolution holds at 5-6MP with 3μm pixel pitch support.

The 97° field of view on a 1/1.7" sensor covers a wide scene without the barrel distortion that plagues most sub-5mm M12 lenses. That -0.7% figure means you can skip software distortion correction entirely in most robotics and video conferencing applications. The 8.8mm designed image circle (9.8mm max) actually covers up to 1/1.6" format sensors like the AR0822 and IMX226 with margin to spare. Use our field of view calculator at https://commonlands.com/pages/camera-field-of-view-calculator to check angles on your specific sensor.

Construction is 4 glass elements plus 4 plastic elements (4G4P) in an aluminum barrel. The lens weighs 8.7g total. Three aperture variants ship stock: F/1.9, F/2.6, and F/4.0. Stopping down to F/2.6 or F/4.0 increases depth of field significantly for fixed-focus installations. Check working distances with our depth of field calculator at https://commonlands.com/pages/camera-depth-of-field-calculator.

The CIL042 is mechanically compatible with FLIR Blackfly S, Allied Vision Alvium, iDS uEye LE, The Imaging Source, and Basler Dart board cameras using standard M12x0.5 mounts. e-con Systems boards need an 8-13mm tall holder. The Commonlands CLA024 lens holder provides a clean mounting solution for custom PCB designs.

Each variant ships with or without a 650nm IR cut filter. Order CIL042-F1.9-M12A650 for daylight use, CIL042-F1.9-M12ANIR for NIR-sensitive applications. All in-stock orders placed before 12 PM PST ship same day from San Diego. Contact us for volume pricing on 100+ units.
