Low Distortion IR Corrected 1.8mm Wide-Angle M12 Lens for Surveillance

CIL019 is a 1.8mm F/1.6 IR corrected wide-angle M12 lens with low TV distortion and a 2G5P optical construction. It fits surveillance and embedded imaging that need wide angular coverage, stable focus from visible through NIR, and less object deformation than a fisheye.

IR correction keeps focal shift under 7 microns MBFL from visible to 850nm. A day/night system that toggles between a cut filter and open NIR mode stays in focus without mechanical adjustment.

The lens covers the 1/2.7" format, which matches sensors such as the Sony IMX662. Resolution is rated for 2-3MP, the designed image circle is 6.6mm, and field of view is 87 degrees at a 3.2mm image circle. This is a wide-angle lens rather than a fisheye, so objects keep a more natural perspective with comparatively low barrel distortion for this focal length class. The F/1.6 aperture also buys real low-light performance in a small package.

One mechanical variant is available. M12P uses BBAR coating on the first lens surface with an AL6061 aluminum cap and a plastic barrel, and it has no ingress protection. The lens also cannot take optical filters internally, so any bandpass or IR cut filter has to sit in the holder.

The CIL019 fits standard M12 board-camera layouts with a 9mm-13mm tall holder. Allied Vision Alvium, FLIR Blackfly S, iDS uEye LE Rev1.1, iDS uEye LE Rev1.2 with part number suffix C-NO, and The Imaging Source M12 boards are mechanically compatible. D3 Camera Module users should confirm fit with D3 Engineering directly.
