Frequently asked questions

What sensors work with the CIL039 3.9mm M12 lens?

The CIL039 covers 1/1.8 inch and 1/2.3 inch sensors, including the ON Semi AR0521, Sony IMX477, and AR1820. Its 8.7mm image circle gives those formats some margin at 8MP+ resolution.

How much distortion does the CIL039 have?

The CIL039 stays under 0.2% TV distortion. That is low enough that most barcode, measurement, and conferencing systems can skip software dewarping.

Is the CIL039 compatible with Raspberry Pi HQ Camera?

Yes, the CIL039 works with the Raspberry Pi HQ Camera using the IMX477. Use CIL039-F2.8-M12A650 when you need a 650nm IR cut filter for standard daylight imaging.

What is the field of view of the CIL039 on a 1/2.3 inch sensor?

The CIL039 gives 77° horizontal field of view on a 1/2.3 inch sensor. Use the Commonlands FoV calculator at field of view calculator if you want the exact number for another sensor.

Does the CIL039 M12 lens ship from the United States?

Yes, in-stock CIL039 lenses ship same day from San Diego, California for orders placed before 12 PM PST.

Are mechanical drawings available for the CIL039?

Yes, mechanical drawings are available on the product page. Contact engineering@commonlands.com if you need STP 3D model files.

The CIL039 is a 3.9mm M12 lens at F/2.8 that covers 1/1.8" to 1/2.3" sensors while resolving 8MP and above. It gives 77° horizontal field of view on a 6.2mm image circle, which is wide enough for barcode readers, conferencing cameras, and general machine vision without the heavy barrel distortion that usually comes with shorter M12 lenses.

Distortion stays below 0.2% TV. That number matters because most systems can skip software dewarping, which saves processing time and avoids extra latency in measurement or decoding pipelines. The 8.7mm image circle also gives you margin on 1/2" sensors like the AR0521.

Hybrid glass and plastic optics keep the lens at 7.0g, so it works well in volume builds where cost and weight both matter. The M12A variant ships standard. Order CIL039-F2.8-M12A650 with the 650nm IR cut filter for daylight machine vision, or CIL039-F2.8-M12ANIR for NIR applications. You can confirm coverage with our field of view calculator at field of view calculator

The lens is mechanically compatible with the Commonlands CLA018 lens holder, e-con Systems S-mount boards (7-11mm tall mount), Allied Vision Alvium, FLIR Blackfly S, iDS uEye LE (Rev1.1 only; Rev1.2 requires removing glass), The Imaging Source M12, and Basler Dart cameras.

Commonlands ships this lens same day from San Diego for orders placed before 12 PM PST. We 100% MTF test every unit. Trioptics test data and mechanical drawings are available on request.
