Frequently asked questions

What sensors work with the CIL052 low distortion M12 lens?

The CIL052 fits 1/1.8″ sensors resolving 16MP+ at 1.4µm pixel pitch. The ON Semiconductor AR2020 is a direct match, and the 9.0mm image circle also covers 1/2″ sensors with the full 70° FoV.

How low is the CIL052 distortion?

Rectilinear distortion is -0.1% at the 7.2mm image circle. That level is low enough for dimensional measurement, barcode scanning, and machine vision inspection without software correction.

What filter options does the CIL052 have?

Commonlands offers four variants: CIL052-F3.4-M12A650 with 650nm IRC, CIL052-F3.4-M12ABP850 with 850nm bandpass for NIR, CIL052-F3.4-M12ANIR with no filter, and CIL052-F3.4-M12B650 with an IP-rated barrel and 650nm IRC.

What lens holder works with the CIL052?

The Commonlands CLA024 is one compatible holder, and other mounts work as well. e-con Systems boards require a 12–15mm tall mount, and Allied Vision, Basler Dart, D3 Engineering, and The Imaging Source M12 cameras are also compatible.

Does the CIL052 M12 lens ship same day from the US?

Yes, Commonlands ships in-stock M12 lenses same day from San Diego, California for orders placed before 12 PM PST.

Is the CIL052 available in an IP67 variant?

Yes, the CIL052-F3.4-M12B650 is available in the IP-rated M12B barrel. The M12A variant does not have an IP rating.

CIL052 is a 5.2mm low-distortion M12 lens for sensors up to 1/1.8" format, resolving 16MP+ at 1.4µm pixel pitch. Rectilinear distortion is -0.1% measured at the 7.2mm image circle. That number is why engineers use this lens for barcode reading, measurement, and PCB inspection where straight lines need to stay straight without software correction.

The 9-element all-glass design gives you a 70° field of view at a fixed F/3.4 aperture. The image circle is 9.0mm as designed and 9.2mm maximum, which leaves margin on 1/1.8" sensors. For the ON Semiconductor AR2020 and similar 16MP sensors, the lens is a direct optical match. The lens weighs 13.1g, and the 12° chief ray angle at 8.9mm works with most BSI CMOS microlens arrays.

The M12A variant uses BBAR coating on the first surface but has no IP rating. You can order CIL052-F3.4-M12A650 with the 650nm IRC filter, CIL052-F3.4-M12ABP850 with an 850nm bandpass for NIR, CIL052-F3.4-M12ANIR without a filter, or CIL052-F3.4-M12B650 in the IP-rated M12B barrel. The IR cut filter is optional across the line.

The lens is compatible with the Commonlands CLA024 lens holder. e-con Systems boards need a 12–15mm tall mount. D3 Engineering, Allied Vision, Basler Dart, and The Imaging Source M12 cameras are compatible. iDS XLS and Raspberry Pi HQ are not mechanically compatible. You can check field of view calculator for angular coverage on your sensor.

The lens ships same day from San Diego for orders before 12 PM PST. Mechanical drawings and STP files are available on request. You can see depth of field calculator for depth of field at your working distance.
