Frequently asked questions
What sensors does the CIL120 12mm M12 lens support?
The CIL120 covers 1/2″ sensors including the OV4689, and it resolves 8MP at 1.85μm pixel pitch. The 8.1mm image circle and 38° field of view at 12.2mm EFL make it a telephoto option in the M12 form factor.
Is the CIL120 actually IP67 rated?
Yes. The CIL120 M12A variant is IP67 sealed with a waterproof aluminum barrel. That rating covers immersion to 1 meter for 30 minutes and full dust ingress protection, so it fits outdoor cameras exposed to rain, humidity, and washdown.
How much distortion does the CIL120 have?
The CIL120 has -3% TV distortion. That is low enough for most machine vision tasks, including license plate recognition and perimeter security, without software correction in typical use.
Which lens holder works with the CIL120?
The recommended match is the Commonlands CLA024 lens holder with 13mm mount height. The CIL120 also fits e-con Systems, Allied Vision Alvium, FLIR Blackfly S, iDS uEye LE, The Imaging Source, and Basler Dart S-mount cameras.
Can the CIL120 replace a front cover glass on outdoor cameras?
Yes. IP67 sealing means the CIL120 can replace a protective front window, which removes one optical surface from the light path. That usually helps contrast and avoids the condensation problems common in windowed outdoor housings.
Does the CIL120 12mm M12 lens ship same day?
Yes. Commonlands ships all in-stock lenses same day from San Diego for orders placed before 12 PM PST. More than 230 units of the CIL120 with 650nm IRC are currently in US stock.
