IR Corrected 12mm M12 Lens for 8MP-12MP 1/1.7" sensors such as OS08A10 and AR0821

The CIL122 is an IR-corrected 12mm M12 lens for 8MP to 12MP sensors in 1/1.7" format, including the OS08A10 and AR0821. It uses a fixed F/2.4 aperture, weighs 7g, and throws a 9.3mm image circle that covers the full sensor diagonal with margin. This is a practical focal length for corridors, doorways, and conveyor sections where you need reach without going narrow.

The CIL122 keeps distortion under 2% TV at the 9.2mm image circle. That level is usually low enough that machine vision systems can skip software correction and still hold geometry well enough for barcode reading, object detection, and many gauging tasks. The 43° field of view is easy to work with because it gives coverage without the perspective exaggeration that short focal lengths add. You can match it to your sensor at field of view calculator.

The optical design uses nine glass elements in an AL6061 aluminum barrel, and the first surface uses BBAR coating to cut reflections. IR correction keeps visible light and 850-940nm NIR light on nearly the same focal plane, which matters for RGBIR sensors like the OX08B40. The system stays sharp across spectral bands without a refocus step.

The M12A variant ships with or without a 650nm IR cut filter. You should order CIL122-F2.0-M12A650 for daylight-only systems, and you should order CIL122-F2.0-M12ANIR for NIR applications. The lens works with e-con Systems, Allied Vision Alvium, FLIR Blackfly S, iDS uEye XLS, The Imaging Source, and Basler Dart board cameras through the Commonlands CLA024 lens holder.
