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.
