Wide-Angle No-Distortion 2mm M12 Lens for 1/2.3" sensors such as IMX477 and IMX908

CIL023 is a wide-angle M12 lens aimed at applications that need broad coverage without fisheye behavior. It uses a 2.2mm effective focal length, a 121° field of view, and an F/2.2 aperture. The lens is specified for a 1/2.3" format with a 7.2mm image circle and 6MP resolution.

The main optical point is distortion control. CIL023 is listed at -5% TV distortion in 4:3, which is much easier to work with than a typical ultra-wide fisheye. If you need a wider view for robotics or embedded vision but still want scenes to look natural and calibration to stay manageable, this is the type of lens to consider.

The construction is hybrid glass/plastic with an AL6061 barrel, and the assembly weighs 9.3g. That gives you a sturdier package than entry-level plastic lenses while keeping size and weight reasonable for board-level cameras. NIR correction also makes it usable in cameras that switch to near-infrared illumination.

CIL023 is offered in two mechanical versions. M12A is a standard non-sealed option, while M12B adds IP67 protection with an all-aluminum cap and barrel. Choose based on whether the lens will live inside an enclosure or face the outside world.
