Frequently asked questions
What sensors does the CIL384 3mm M12 lens support?
The CIL384 is built for 1/2.5″ sensors including the Sony ISX031 and ON Semiconductor AR0234. It resolves 2MP at 3.45μm pixel pitch across a 6.7mm image circle.
Is the CIL384 IP69K rated for automotive exterior applications?
Yes. The CIL384 carries an IP69K rating with a sealed all-glass, all-metal barrel that is meant for high-pressure washdown, dust ingress, and automotive temperature cycling.
How much distortion does the CIL384 have at -36%?
The -36% barrel distortion is significant, but that is normal for a 3mm-class automotive wide-angle. Surround-view and ADAS systems usually correct it in software, and you should look at CIL329 or CIL327 if lower distortion matters more than coverage.
What cameras are mechanically compatible with the CIL384?
FLIR Blackfly S, Allied Vision Alvium, iDS uEye LE, The Imaging Source M12, and Basler Dart S-mount cameras all mount the CIL384 directly. works with the Commonlands CLA019 holder and other compatible mounts.
Does the CIL384 ship same day from the US?
Yes. Orders placed before 12 PM PST ship same day from the San Diego warehouse. Contact Commonlands for production pricing.
Can the CIL384 be used for surround-view ADAS camera systems?
Yes. The 116° FoV, IP69K rating, F/1.6 aperture, and ISX031 or AR0234 compatibility make the CIL384 a strong fit for surround-view, parking assist, and rear-view modules.
