Wide-Angle Fisheye M12 Lens \| For up to 12MP sensors w/1.55um pixels such as IMX377, IMX412

The CIL227 is a 2.7mm fisheye M12 lens with 190° diagonal field of view at an 8.0mm image circle. It uses a fixed F/2.5 aperture, an 8G all-spherical all-glass design, an aluminum barrel, and an 8g package, so it gives full fisheye coverage without getting bulky.

The lens resolves 12MP at 1.55μm pixel pitch on sensors such as the Sony IMX377 and IMX412. That is enough for common 1/2.3" and 1/2" boards that need real resolution across a very wide field instead of just a big angle number. Distortion is -11% F-Θ, which is normal at 190°. On a 1/2.3" sensor, you get about 140° horizontal coverage while keeping the full 190° on the diagonal. The 7.8mm designed image circle covers 1/2" format cleanly.

All-spherical glass elements keep cost lower than more exotic fisheye designs and still hold up through temperature cycling. The lens comes in two mechanical versions. M12A is unsealed, and M12B is IP67-rated for exterior-facing applications. Both versions accept 660nm IRC filters or ship without a filter for NIR-sensitive configurations.

The lens mounts with the Commonlands CLA024 lens holder. It is compatible with e-con Systems boards using a 10-14mm holder, Allied Vision Alvium, FLIR Dragonfly S USB3, iDS uEye LE, The Imaging Source, and D3 Camera Modules. Rev1.1 of iDS uEye LE works directly, while Rev1.2 requires part numbers ending in C-NO. You can calculate field of view on your sensor at field of view calculator

Commonlands ships this lens same day from San Diego before 12 PM PST. We 100% MTF test every unit on Trioptics equipment at our ISO 9001:2015 facility. Depth of field planning is available at depth of field calculator
