Frequently asked questions

What sensors work with the CIL326 2.9mm M12 lens?

The CIL326 fits 1/2.7 inch sensors up to 3MP, including the Sony IMX322 and IMX390. Its 6.8mm designed image circle covers those formats with margin.

How wide is the CIL326 field of view?

The CIL326 gives 146° field of view at the 6.6mm image circle. You can check the exact horizontal and vertical angles for your sensor at field of view calculator

Is the CIL326 good for automotive surround-view cameras?

Yes. The F/1.45 aperture and 146° field of view make the CIL326 a strong choice for automotive surround-view, in-cabin monitoring, and other ADAS cameras that need wide coverage in low light.

What is the distortion on the CIL326 M12 lens?

The CIL326 has -8% F-Theta distortion at 6.6mm. That level is typical for a wide automotive lens, and most ADAS software pipelines can correct it.

Does the CIL326 ship same day from the US?

Yes. Orders placed before 12 PM PST ship same day from Commonlands in San Diego, California.

What lens holder works with the CIL326?

The Commonlands CLA020 holder is one compatible mount for the CIL326, and other M12 mounts work as well. The lens also fits e-con Systems boards with a 13mm tall mount, Allied Vision Alvium, FLIR Blackfly S, iDS uEye XLS, The Imaging Source M12, and Basler Dart cameras.

The CIL326 is a 2.9mm EFL M12 lens for 1/2.7" sensors up to 3MP like the IMX322 and IMX390. It gives you a 146° field of view across a 6.6mm image circle, so the lens covers the scene widths that surround-view and in-cabin systems need. At F/1.45, it also keeps more light on the sensor when automotive and surveillance scenes get dim.

Distortion is -8% F-Theta at 6.6mm. That number is wide-angle territory, but most ADAS pipelines correct it without trouble and still prefer the extra coverage. The 6.8mm designed image circle, with a 7.2mm maximum, covers 1/2.7" sensors with margin, so you are not pushing the optics right to the edge of coverage.

The lens uses seven all-glass elements in an AL6061 aluminum barrel and weighs 5.5g. The M12A variant includes BBAR coating on the first surface, which helps when headlights or sun angle would otherwise raise flare. You can order CIL326-F1.4-M12A650 if you need the 650nm IR cut filter version.

The lens is mechanically compatible with Commonlands CLA020 holders, e-con Systems boards with a 13mm tall mount, Allied Vision Alvium, FLIR Blackfly S, iDS uEye XLS, The Imaging Source, and Basler Dart S-mount cameras. You can Calculate your field of view to verify coverage before you commit.

Commonlands ships in-stock parts same day from San Diego for orders placed before 12 PM PST. You can contact the optical engineering team for volume pricing or application support.
