Frequently asked questions
What sensors does the CIL050 5mm M12 lens support?
The CIL050 has a 9.3mm image circle and supports 12MP resolution, so it pairs with sensors up to the 1/1.8 inch format. Common pairings include the Sony IMX335, Sony IMX462, and Onsemi AR0521. Model the exact view on your sensor with the Commonlands field of view calculator.
How much distortion does the CIL050 have?
The CIL050 has -17% TV distortion, so straight lines bend noticeably near the edges. That trade is normal for a 120 degree wide-angle design and works fine for robotics navigation and surveillance. For measurement or inspection, plan on software correction or choose a low-distortion lens instead.
What is the image circle of the CIL050?
The image circle is 9.3mm, which covers 1/2 inch and 1/1.8 inch sensors with margin. The lens delivers its 120 degree diagonal field of view at that circle.
Is the CIL050 compatible with the IMX226 sensor?
Mostly, with one caveat. The Sony IMX226 has a 9.41mm diagonal and the CIL050 image circle is 9.3mm, so the extreme corners sit just outside the illuminated circle. Surveillance and navigation systems usually accept that slight corner falloff. If your application needs fully illuminated corners, contact engineering@commonlands.com for an alternative.
Which lens holder fits the CIL050 M12 lens?
The Commonlands CLA020 lens holder with 20mm mounting hole spacing is the direct fit. The lens also works with e-con Systems boards using a 9-13mm holder, Allied Vision Alvium, FLIR Blackfly S, iDS uEye LE, The Imaging Source, and Basler Dart S-mount cameras.
Does the CIL050 ship same day from the United States?
Yes. In-stock CIL050 lenses ship same day from San Diego, California for orders placed before 12 PM PST, and every lens is MTF tested before it ships.
