10mm M12 Lens \| 10mm S-Mount Lens for up to 4MP

The CIL104 is a 10.4mm M12 lens for 1/2.5" sensors resolving 3–4MP. It gives you a 36° field of view at the 6.6mm image circle, which lands in the gap where 8mm is often too wide and 12mm is often too tight. That framing works well for barcode readers, license plate recognition, and mid-range inspection stations that need a narrower view without moving to a larger mount.

Distortion is -0.014%, which is close enough to zero that most OCR and measurement systems can skip software correction. The 7.2mm designed image circle, with a 9.0mm maximum, covers 1/2.5" sensors cleanly and can stretch a bit larger if you can tolerate some corner fall-off. Resolution stays in the 3–4MP range, so the lens matches the sensor class it is aimed at.

The barrel uses machined AL6061 aluminum, and the maximum outside diameter stays at 12mm. That size still fits tight camera enclosures where many telephoto M12 lenses start to get awkward. The lens weighs 3.5g, and you can use our field of view calculator at field of view calculator to check coverage on your sensor.

The mechanical option here is M12A. You can order CIL104-F3.8-M12A650 with a 650nm IR cut filter or CIL104-F3.8-M12ANIR without a filter. The lens fits e-con Systems, Allied Vision Alvium, FLIR Blackfly S, iDS uEye LE, and The Imaging Source M12 cameras when you The Commonlands CLA018 lens holder is one compatible mounting option.
