Frequently asked questions
What sensors work with the CIL820 2.1mm M7 lens?
The CIL820 fits 1/4 inch sensors up to 2MP, including the ON Semiconductor AR0144. Its 4.5mm image circle covers the full 1/4 inch format with margin.
How much distortion does the CIL820 have?
The CIL820 has +16% F-Theta distortion, which is pincushion distortion. That level is normal for a wide 2.1mm M7 lens, and machine vision measurement work will usually need software correction.
Is the CIL820 compatible with e-con Systems cameras?
Yes, but the fit is not direct. The CIL820 uses an M7 mount, so e-con Systems standard S-mount boards need the Commonlands CLA021 adapter.
What is the difference between CIL820-F2.7-M07A650 and CIL820-F2.7-M07ANIR?
The CIL820-F2.7-M07A650 version includes a 650nm IR cut filter for daylight color imaging. The CIL820-F2.7-M07ANIR version ships without a filter, which is the better choice for NIR illumination or multispectral work.
How small is the CIL820 M7 lens?
The CIL820 weighs 1.0g and has a 10.9mm total track length. That size makes it one of the smaller wide-angle options for embedded vision and IoT hardware.
Does the CIL820 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.
