Frequently asked questions

What sensors does the CIL334 3.5mm M12 lens support?

The CIL334 supports 1/1.7 inch and 1/1.8 inch sensors at 6–8MP resolution with 2.4μm pixel pitch. The 9.2mm image circle covers the full diagonal of those formats.

How much distortion does the CIL334 wide-angle lens have?

The CIL334 has -7% F-Θ distortion at the 8.0mm image circle. That is typical for wide-angle machine vision and drone cameras, and software correction can clean it up when needed.

Is the CIL334 weatherproof for outdoor and drone use?

Yes. The M12C variant is IP67 rated and has a hydrophobic coating on the first lens surface. It handles rain, spray, and condensation well in outdoor and aerial robotics use.

How heavy is the CIL334 M12 lens?

The CIL334 weighs 4.3g and has a 19.5mm total track length. That makes it a good fit for UAV and other weight-constrained payloads. Plan working distances with our depth of field calculator at depth of field calculator

Does the CIL334 ship same day from the United States?

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

What cameras are mechanically compatible with the CIL334?

The CIL334 is mechanically compatible with Commonlands CLA019 holders, FLIR Blackfly S, Allied Vision Alvium, iDS uEye LE, The Imaging Source M12, and Basler Dart S-mount cameras.

The CIL334 is a 3.5mm wide-angle M12 lens that covers 1/1.7" and 1/1.8" sensors in 16:9 mode. At F/2.2, the hybrid glass/plastic design resolves 6–8MP at 2.4μm pixel pitch across a 9.2mm image circle, so it fits the full diagonal of these larger embedded sensors without moving to a bigger mount.

The lens gives 141° at the 8.0mm image circle, and distortion is -7% F-Θ at that same image height. That is a workable number for wide-angle embedded vision, and F-theta is the right way to judge a fisheye-adjacent design because it shows how far edge pixels move from an equidistant projection. This lens makes sense for drone downward-look cameras, panoramic stitching, and wide-area monitoring. Check coverage the field of view calculator

The CIL334 weighs 4.3g and has a 19.5mm total track length. That low mass matters on aerial robotics and other payloads where the lens competes directly with battery and sensor weight. The single M12C variant ships IP67 sealed and adds a hydrophobic coating on the first surface, so rain, condensation, and spray roll off instead of beading.

The mechanics match Commonlands CLA019 lens holders, FLIR Blackfly S, Allied Vision Alvium, iDS uEye LE, The Imaging Source, and Basler Dart S-mount cameras. An 8–13mm tall holder works for standard e-con Systems S-mount boards.

Commonlands ships this lens same day from San Diego before 12 PM PST. Every unit is 100% MTF tested. Contact our US-based optical engineers for volume pricing or custom integration support.
