190° Compact M8 / M12 Fisheye Lens for 3MP-5MP Sensors

The CIL818 is the compact option when you need fisheye coverage in either M8A, M12A, or M12B mechanics. EFL is 1.75mm, aperture is F/2.05, and the specification table gives 190° at a 5.1mm image circle with a full image circle of 5.3mm. The page also positions it as a 195°/200° class miniature fisheye, which is why it shows up in ultra-wide embedded camera searches.

This lens is built for sensors from 1/3.6" to 1/1.8" with 3-5MP resolution and 3μm pixels. If you are working with AR0230-class sensors and you need more coverage without a bulky lens stack, this is the right direction. The small mass matters too: the M8 version is just 1.4g.

Construction is a hybrid glass/plastic optical design. The M8 version uses an AL6061 cap and barrel. The M12 version uses an AL6061 cap with a plastic barrel in the M12A version, while M12B moves to an AL6061 barrel. All listed variants are IP67 rated and use BBAR on lens 1 surface 1.

Compatibility is narrower than the CLA024-class M12 lenses. The recommended holder is CLA017, and e-con Systems boards with a 5-7mm holder height are the cleanest match. Allied Vision, FLIR, iDS uEye LE, and The Imaging Source are listed as not compatible on the page. Basler requires an inquiry rather than a straight yes.
