Frequently asked questions

What sensors work with the CIL872 7mm M12 lens?

The CIL872 is made for 1/2″ sensors like the ON Semiconductor MT9P031, and it resolves 5MP at 2.2μm pixel pitch. The 8.0mm image circle covers 1/2″ format with margin.

How much distortion does the CIL872 have?

The CIL872 has less than 1% TV distortion. That is low enough for barcode scanning, dimensional measurement, and machine vision inspection without software correction in many setups.

What is the CIL872 image circle and field of view?

The CIL872 produces an 8.0mm image circle with a 48° diagonal field of view measured at the 6.3mm active area. Use the calculator at field of view calculator to model your specific sensor.

What lens holder does the CIL872 use?

The CIL872 works with the Commonlands CLA018 holder and other compatible mounts. For e-con Systems boards, pair it with the CLA021 adapter.

Does the CIL872 come with an IR cut filter?

Two variants are available. CIL872-F2.8-M12A650 includes a 650nm IR cut filter for standard daylight use, and CIL872-F2.8-M12ANIR ships without a filter for NIR-sensitive applications.

Does the CIL872 ship same day from San Diego?

Yes. Commonlands ships the CIL872 same day from San Diego for orders placed before 12 PM PST.

The CIL872 is a compact 7.2mm M12 lens for 1/2" sensors like the MT9P031. At F/2.8 it resolves 5MP at 2.2μm pixel pitch, and it gives a 48° diagonal field of view across a 6.3mm image circle. The 2g weight also makes it easy to use in small embedded systems where the lens cannot dominate the mechanical stack.

Distortion stays under 1% TV. That is low enough for measurement, barcode reading, and inspection work where geometry matters. The 8.0mm image circle gives you extra margin on 1/2" sensors, which helps with coverage tolerance. Calculate field of view at field of view calculator

The optics use a hybrid glass/plastic design in an AL6061 aluminum barrel with BBAR coating. The M12A variant ships without ingress protection, so it is a better fit for indoor or enclosed systems where weather sealing would only add cost and bulk.

The lens is mechanically compatible with the Commonlands CLA018 lens holder with 18mm spacing. e-con Systems boards work with the CLA021 adapter. Allied Vision Alvium, FLIR Blackfly S, iDS uEye LE, and The Imaging Source boards are not directly compatible, so you should check the camera datasheet before you lock the design.

You can order CIL872-F2.8-M12A650 with the 650nm IR cut filter for daylight imaging, or CIL872-F2.8-M12ANIR without the filter for NIR applications. Commonlands ships this lens same day from San Diego before 12 PM PST. Check depth of field at depth of field calculator
