Frequently asked questions

What sensors work with the CIL027 2.7mm M12 lens?

The CIL027 resolves 8MP at 2.2μm pixel pitch and covers sensors up to 1/1.8 inch format. Sony IMX178 and IMX265 are solid matches. Check field of view at field of view calculator

How much distortion does the CIL027 have?

The CIL027 has -1.5% TV distortion measured at 4:3 aspect ratio. That is low enough for barcode reading, dimensional measurement, and inspection without software correction.

What is the CIL027 field of view on a 1/2.3 inch sensor?

The CIL027 gives 100° horizontal field of view on a 1/2.3 inch sensor at the 6.3mm image circle. Its usable image circle extends to 7.4mm, with 9.0mm maximum.

What lens holders are compatible with the CIL027?

Use the Commonlands CLA018-LCP with 18mm hole spacing. e-con Systems boards need a 9-13mm tall holder, and FLIR Blackfly S, Allied Vision Alvium, iDS uEye XLS, The Imaging Source, and Basler Dart are mechanically compatible.

Does the CIL027 come with an IR cut filter?

Yes, the CIL027-F2.8-M12A650 includes a 650nm IR cut filter for daylight use. The CIL027-F2.8-M12ANIR ships without a filter for NIR-sensitive applications.

Does the CIL027 ship same day from the United States?

Yes, in-stock CIL027 lenses ship same day from San Diego, California for orders placed before 12 PM PST. Every CIL027 is 100% MTF tested before shipping.

The CIL027 is a 2.7mm wide-angle M12 lens with 100° field of view on 1/2.3" sensors and -1.5% TV distortion. At F/2.8 fixed aperture, it resolves 8MP at 2.2μm pixel pitch on sensors such as the Sony IMX178 and IMX265. Its 7.4mm usable image circle covers up to 1/1.8" format.

That distortion number is the reason to buy this lens. Many 2.7mm M12 lenses land closer to 3-5% barrel distortion, which pushes you toward software correction if straight lines matter. The CIL027 stays low enough that barcode scanning, measurement, and inspection systems can often run on embedded hardware without a dewarp step.

The lens uses 5G2P optics in an AL6061 aluminum barrel. Order CIL027-F2.8-M12A650 with the 650nm IR cut filter, or CIL027-F2.8-M12ANIR without a filter for NIR applications. BBAR coating on the first lens surface helps reduce flare.

The lens is mechanically compatible with FLIR Blackfly S, Allied Vision Alvium, Basler Dart, iDS uEye XLS, and The Imaging Source board cameras. The recommended mount is the Commonlands CLA018 with 18mm hole spacing. e-con Systems boards need a 9-13mm tall holder.
