Frequently asked questions
What sensors work with the CIL081 8mm M12 lens?
The CIL081 fits sensors larger than 1/1.7 inch with a 12mm image circle. That coverage includes common 1/1.8 inch and 2/3 inch formats with margin.
How much distortion does the CIL081 have?
The CIL081 has 1% TV distortion. That level is low enough for barcode reading, dimensional measurement, and general machine vision without software correction in most cases.
What is the image circle of the CIL081 8mm M12 lens?
The CIL081 projects a 12mm image circle. That size is larger than most M12 lenses, which is why the lens works on bigger sensors where many S-mount optics stop covering the corners.
Does the CIL081 come with an IR cut filter?
Yes. You can order CIL081-F2.0-M12A650 with a 650nm IR cut-off filter or CIL081-F2.0-M12ANIR without a filter for NIR-sensitive setups.
What cameras are compatible with the CIL081?
The CIL081 is mechanically compatible with e-con Systems standard S-mount boards, Allied Vision Alvium, FLIR Blackfly S, iDS uEye LE, The Imaging Source M12, and Basler Dart cameras. The Commonlands CLA024 lens holder provides the correct mount for board-level use.
Does the CIL081 ship same day from the US?
Yes. Commonlands ships in-stock lenses same day from San Diego, California for orders placed before 12 PM PST.
