Frequently asked questions

What sensors does the CIL355 5.5mm M12 lens support?

The CIL355 fits 1/2.7 inch sensors up to 1.3MP, including the ON Semiconductor AR0234. Its 7.3mm image circle covers the full 1/2.7 inch format.

Is the CIL355 rated for automotive use?

Yes. The CIL355 carries IP6K9K ingress protection, so it is dust-tight and resists high-pressure, high-temperature water jets used in automotive testing.

What is the CIL355 field of view?

The CIL355 gives 89° field of view at the 7.2mm image circle. Your exact horizontal and vertical angles depend on sensor size, so you should verify them at field of view calculator

What cameras work with the CIL355?

The CIL355 is mechanically compatible with e-con Systems, Allied Vision Alvium, FLIR Blackfly S, iDS uEye LE, The Imaging Source, and Basler Dart S-mount cameras. The Commonlands CLA019 lens holder sets the proper mounting height.

Does the CIL355 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.

Can I use the CIL355 for night vision with IR illumination?

Yes. You can order CIL355-F1.8-M12ANIR if you want the version without an IR cut filter. That version pairs well with 850nm or 940nm IR illumination for night vision work.

The CIL355 is a 5.5mm automotive M12 lens for 1/2.7" sensors up to 1.3MP. It gives you an 89° field of view at the 7.2mm image circle, which is wide enough for forward-facing ADAS, surround-view, and parking assist cameras without going all the way to fisheye territory. At F/1.8, the lens also keeps exposure under control in tunnels, at dusk, and in poorly lit parking structures.

Distortion is -9% TV barrel. That is too high for raw geometry work, but ADAS camera pipelines usually correct distortion in software anyway, so the number is not a problem in the use cases this lens targets. The 5G all-glass design in an AL6061 barrel also holds focus through the -40°C to +85°C thermal range that automotive hardware sees.

The IP6K9K rating means the lens is dust-tight and resistant to high-pressure, high-temperature water jets. That rating matters if the camera sits outside the cabin or anywhere near washdown exposure. The BBAR coating on the first surface reduces flare from headlights, and you can use our field of view calculator at field of view calculator to check coverage on your sensor.

The lens fits e-con Systems, Allied Vision Alvium, FLIR Blackfly S, iDS uEye LE, The Imaging Source, and Basler Dart boards with the Commonlands CLA019 lens holder. You can order CIL355-F1.8-M12A650 with a 660nm IR cut filter or CIL355-F1.8-M12ANIR without a filter.

Commonlands ships in-stock parts same day from San Diego before 12 PM PST. You can contact engineering@commonlands.com for automotive qualification data and volume pricing.
