12.5mm M12 Lens for sensors up to 1/2" sensors such as IMX477

The CIL125 is a 12.5mm telephoto M12 lens for sensors up to 1/2" format. It comes in F/2.4, F/3.6, and F/8.0 versions, so you can choose the balance between light, resolution, and depth of field instead of forcing one aperture to do every job.

The F/2.4 variant resolves 12MP at 1.55μm pixel pitch on sensors like the IMX477. The F/3.6 variant resolves 8MP at 1.85μm, and the F/8.0 variant pushes depth of field furthest while resolving 3MP. Those tradeoffs are straightforward: the faster lens helps when light is limited, while the slower lens helps when you need more of the scene in focus at a fixed working distance.

The lens gives 35° field of view on a 7.9mm image circle, and distortion stays at only -1.4% rectilinear. That combination makes sense for license plate recognition, inspection at longer working distance, and narrow-field monitoring where straight lines still need to look right. The 8.0mm image circle covers 1/2" sensors cleanly.

Hybrid glass and plastic construction keeps weight at 7g. The M12 thread fits any standard M12x0.5 camera board. Order CIL125-F2.4-M12A650, CIL125-F3.6-M12A650, or CIL125-F8.0-M12A650 with the 650nm IR cut filter for daylight machine vision, or order the versions without a filter for NIR applications.
