230° M12 Fisheye Lens for up to 1/1.8" sensors such as IMX677 and IMX147

The CIL213 is a 1.2mm ultra-fisheye M12 lens with a full 230° field of view on a 4.5mm image circle. It uses ten all-glass elements in an aluminum barrel, a fixed F/2.3 aperture, and a 21g package. That is heavier than most M12 fisheyes, but the extra glass is what it takes to get 230° coverage while still resolving 12MP at 1.55μm pixel pitch on 1/1.8" sensors such as the Sony IMX677 and IMX147.

The lens uses -9% F-Θ distortion, which puts the projection between equidistant and equisolid. That matters because the 230° field reaches behind the lens plane, so two cameras mounted back-to-back can overlap enough for 360° stitching with some margin. The compact 4.5mm image circle also helps keep the overall package smaller than you would expect for this field angle.

The CIL213 ships IP65-rated out of the box. It is sealed against dust ingress and water jets, so outdoor surveillance and exterior monitoring do not need extra weatherproofing around the lens. The aluminum barrel and BBAR-coated first surface also hold up better outdoors than cheaper plastic builds.

The lens mounts with the Commonlands CLA024 lens holder. It is compatible with e-con Systems boards using an 8-13mm holder, Allied Vision Alvium, FLIR Blackfly S, and Basler Dart. iDS uEye LE Rev1.1 works, but Rev1.2 does not. The Imaging Source requires removing the glass window first.

Commonlands ships this lens same day from San Diego before 12 PM PST. Every CIL213 is 100% MTF tested. You can calculate your field of view
