2.8mm Molded Glass Asphere Low Distortion Lens for up to 1/2.5" sensors such as IMX577

The CIL093 is a 2.8mm wide-angle M12 lens that resolves 5MP at 2.2μm pixel pitch on 1/2.5" sensors like the IMX577. The optical stack is the reason to buy it. The design uses seven glass elements plus two molded glass aspheres in an AL6061 barrel, and it avoids plastic optics entirely.

The all-glass construction keeps focus more stable across a -20°C to 60°C operating range than typical plastic-element lenses do. The CIL093 gives you 112° across the 7.6mm image circle, and distortion stays at -3% TV. That is low for a lens this wide. Many competing 2.8mm M12 lenses in this price range land around 5-10% barrel distortion, so edge detection and object tracking need less correction here.

The optics are also NIR corrected, so visible and near-infrared wavelengths stay on nearly the same focal plane. That matters in day-night cameras using IR illumination because the image stays sharp at 850nm without a mechanical refocus step. The fixed F/2.4 aperture gives the lens enough speed for indoor and outdoor use, and the full assembly weighs 9.1g.

The M12A variant ships with or without a 650nm IR cut filter. You should order CIL093-F2.4-M12A650 for daylight-only systems, and you should order CIL093-F2.4-M12ANIR for NIR and day-night applications. The lens works with e-con Systems, Allied Vision Alvium, FLIR Blackfly S, iDS uEye LE, The Imaging Source, and Basler Dart cameras through the Commonlands CLA018 lens holder. iDS uEye Rev1.2 requires the part number ending in "C-NO".

All in-stock units ship the same day from San Diego when you order before 12 PM PST. Every CIL093 is 100% MTF tested at our ISO 9001:2015 facility. Contact engineering@commonlands.com if you need volume pricing or help with depth of field analysis. The calculator is at depth of field calculator
