3.6mm M12 Lens with Hydrophobic Coating For Up To 1/2.4" such as AR0233, AR0230, AR0234

Wide-Angle 3.6mm M12 Lens

The CIL336 is an automotive-grade 2MP-3MP wide-angle 3.6mm M12 lens which provides ~90°-95° Horizontal Field of View on 1/2.5" sensors such as the AR0230. The all-glass all-metal lens is IP6K9K rated with hydrophobic coating on the front lens element. Combined with the F/1.9 aperture, this lens is great for robotic camera systems with direct exposure to the elements.

Frequently asked questions

What sensors work with the CIL336 3.6mm M12 lens?

The CIL336 supports 1/2.4 inch and 1/2.5 inch sensors including the ON Semiconductor AR0233, AR0230, and AR0234, and it resolves 2-3MP at 3µm pixel pitch.

What is the IP rating of the CIL336?

The CIL336 is IP6K9K rated. That is the highest protection level against high-pressure, high-temperature water jets and dust ingress, and the lens also uses a hydrophobic coating on the front element.

How much distortion does the CIL336 have?

The CIL336 has -5.5% F-Theta distortion at the 7.6mm image circle. For most automotive and robotics work, standard software correction is enough.

What is the difference between CIL336-F1.9-M12A650 and CIL336-F1.9-M12ANIR?

CIL336-F1.9-M12A650 includes a 650nm IR cut filter for visible-light imaging. CIL336-F1.9-M12ANIR ships without the filter and is meant for sensors operating in the near-infrared range.

Which cameras are mechanically compatible with the CIL336?

The CIL336 works with the Commonlands CLA021 holder with a 7-10mm tall mount, e-con Systems S-mount boards, Allied Vision Alvium, FLIR Blackfly S, iDS uEye LE, The Imaging Source M12, and Basler Dart cameras.

Does the CIL336 ship same day from the US?

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

The CIL336 is a 3.6mm M12 lens for automotive and outdoor robotics on 1/2.4" sensors like the ON Semiconductor AR0233, AR0230, and AR0234. At F/1.9 it gives you more light for HDR imaging, and the 128° field of view at the 7.6mm image circle covers a wide scene while keeping distortion to -5.5% F-Theta.

The lens is IP6K9K rated and uses a hydrophobic coating on the front element. That rating matters when the camera has to survive high-pressure, high-temperature water jets instead of just light spray. The all-glass construction sits in an aluminum barrel, and the package stays light at 3.7g with a 17.9mm total track length, so it still fits aerial robotics payloads and tight automotive camera modules.

The M12A variant ships with an AL6061 cap and barrel. You can order CIL336-F1.9-M12A650 with the 650nm IR cut filter for visible-light imaging, or CIL336-F1.9-M12ANIR without the filter for near-IR sensor configurations.

The lens is mechanically compatible with the Commonlands CLA021 lens holder with a 7–10mm tall mount, e-con Systems standard S-mount boards, Allied Vision Alvium, FLIR Blackfly S, iDS uEye LE, The Imaging Source M12, and Basler Dart cameras. iDS uEye LE Rev1.2 requires removing the glass window.
