3.5mm M12 Lens for 8MP+ 1/1.8" sensors such as IMX178, IMX678, and IMX334

The CIL333 is a 3.5mm wide-angle M12 lens for 1/1.8" sensors up to 10MP, including the Sony IMX178, IMX678, and IMX334. It gives you 136° field of view at F/2.4 with an 8.0mm image circle, so you can cover a lot of scene without giving up the full sensor class. The lens uses eight all-glass elements in an aluminum barrel and weighs 67g, which tells you this is not a toy wide-angle optic.

The 8.8-9.0mm image circle oversizes the 1/1.8" format, and that extra margin helps keep the edges cleaner. The total track length is 22.7mm. Resolution holds at 6-8MP with 2.2μm pixel pitch, which is a useful compromise when you need wide coverage, decent detail, and a package short enough to fit real hardware.

The distortion is -5% F-Θ measured at 9.0mm. That is a reasonable number for a 136° lens, and it keeps angular sampling more uniform than a rectilinear design at the same width. The available mechanical variants are M12A for the standard version and M12B for IP69-rated outdoor and washdown use. Both use AL6061 barrel and cap with BBAR on lens 1 surface 1. Order the 650nm IRC filter or the NIR variant based on your spectral requirements.

The CIL333 fits FLIR Blackfly S, Allied Vision Alvium, iDS uEye LE Rev1.1 and Rev1.2, The Imaging Source M12, and Basler Dart S-Mount cameras. The Commonlands CLA024 lens holder works for e-con Systems boards that need a 9-13mm tall mount, and other compatible mounts are available. If depth of field, start with the calculator
