Frequently asked questions
What sensors does the CIL339 4mm automotive M12 lens support?
The CIL339 covers 1/1.7 inch sensors resolving 10-12MP at 1.85μm pixel pitch, including the AR0823, OX08B40, and IMX678. Its designed image circle is 9.3mm, with a 10.4mm maximum.
How much distortion does the CIL339 wide-angle lens have?
The CIL339 has -3% F-Theta distortion at the 9.3mm image circle. That is unusually low for a 140° field of view lens, so many navigation and detection systems can skip software correction.
Is the CIL339 rated for automotive and harsh environments?
Yes. The CIL339 is IP6K9K rated with a hydrophobic coating, so it handles pressure washing, dust ingress, rain, and automotive temperature cycling.
What cameras are mechanically compatible with the CIL339?
The CIL339 works with e-con Systems boards using the included aluminum lens holder. It also fits The Imaging Source and Basler Dart S-mount cameras through the Commonlands CLA024 mount, and it does not fit Allied Vision Alvium, FLIR Blackfly S, or iDS uEye LE.
Does the CIL339 ship same day from the US?
Yes. Orders placed before 12 PM PST ship same day from San Diego.
What is the optical construction of the CIL339?
The CIL339 uses a 4G+3MG construction with four glass elements and three molded glass aspheres. That design helps it hold resolution and thermal stability at automotive temperature extremes.
