IP67 M12 Miniature Fisheye Lens \| 168°@6.0mm and 5MP up to 1/1.7" such as AR0521

The CIL222 is a 2.2mm fisheye M12 lens that gives you 168° at a 6.0mm image circle. At F/2.0, with all-glass all-metal construction and a 4.8g weight, it fits applications that need nearly full-scene coverage without a bulky front end. The lens resolves 5–6MP at 1.85μm pixel pitch on sensors up to 1/1.7" format like the AR0521.

Distortion is -6.8% F-Θ at the 6.0mm image circle. For a 168° fisheye, that is well controlled, and the near-linear F-theta behavior makes dewarping easier in a vision pipeline. The 6.2mm image circle also gives you a little margin beyond the nominal 6.0mm spec. This lens is the one to use for panoramic surveillance, robot navigation, and other jobs where a single camera needs to see almost everything. Calculate coverage at field of view calculator

The optics use all-glass elements in an aluminum barrel, and the total track length is 16.7mm. That package is genuinely small for this class, so you get fisheye coverage without moving to a much larger lens. The lack of plastic elements also helps the focus stay put through outdoor temperature swings.

The M12A variant ships IP69K rated with BBAR coating. You can order CIL222-F2.0-M12A650 with the 650nm IRC for daylight, CIL222-F2.0-M12ANIR for NIR-sensitive sensors, or CIL222-F4.0-M12A650 for a stopped-down variant with greater depth of field. The lens is compatible with Commonlands CLA018 lens holders and e-con Systems boards with 7–9mm tall mounts. Allied Vision Alvium, FLIR Blackfly S, iDS, and The Imaging Source cameras are not mechanically compatible.
