Frequently asked questions
What sensors work with the CIL522 12mm C-mount lens?
The CIL522 fits 2/3″ sensors up to 3MP at 4.2µm pixel pitch, including the Sony IMX264 and IMX547. At F/2.8, it resolves down to 2.74µm pixel pitch for higher resolution sensors.
What is the aperture range of the CIL522?
The aperture adjusts from F/1.4 to F/16. You can run it wide open at F/1.4 for low-light or high-speed work, or you can stop down when you need more depth of field. You can use depth of field calculator to estimate DoF at your working distance.
How much distortion does the CIL522 have?
Distortion is 0.4% from rectilinear across the 11mm image circle. That level is low enough for most machine vision applications without software correction.
What is the CIL522 minimum working distance?
The minimum working distance is 150mm. The CIL522 focuses from 150mm to infinity.
Does the CIL522 12mm C-mount lens ship from the US?
Yes, Commonlands ships in-stock lenses same day from San Diego, California for orders placed before 12 PM PST.
Are mechanical drawings available for the CIL522?
