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.
