All Glass No-Distortion 4mm M12 Lens for up to 1/2" sensors such as IMX577 IMX477

The CIL038 is a 3.85mm all-glass M12 lens for 1/2" sensors up to 5MP at 3μm pixel pitch. It gives you an 85° field of view with less than 1% TV distortion at the 7.0mm image circle, which is the combination people usually want and rarely get in a compact wide-angle lens. The eight spherical glass elements sit in an aluminum barrel, so the mechanics feel like industrial hardware instead of consumer camera leftovers.

This lens makes sense when wide coverage matters but heavy software correction does not. The 7.8mm designed image circle and 8.2mm max image circle cover 1/2.3" sensors like the IMX577 and IMX477, so the CIL038 works well in Raspberry Pi HQ Camera builds and industrial systems that need straight geometry.

The fixed F/3.0 aperture gives up some light, and that tradeoff is worth stating plainly. You get more depth of field in return, which helps when everything from 300mm to 1m needs to stay in focus. You can estimate that tradeoff at depth of field calculator.

The available mechanical variant is M12A, which uses BBAR coating on the first lens surface and an AL6061 aluminum barrel without ingress protection. Order CIL038-F3.0-M12A650 with 650nm IRC or CIL038-F3.0-M12ANIR for NIR applications. The lens mounts with a Commonlands CLA024 holder and fits FLIR Blackfly S, Allied Vision Alvium, iDS uEye LE, The Imaging Source, and D3 Engineering camera modules.
