2.4mm F-Theta Lens With 156° FoV and IP67+

CIL924 is a 2.4mm F/2.4 M12 wide-angle lens with a 156° field of view and +0.5% F-Theta distortion at a 6.4mm image circle. That projection is the main reason to pick it, because the angular mapping stays very close to the target across the frame instead of drifting into generic wide-angle behavior.

The lens covers sensor formats up to 1/2.5" and is specified for 5MP imaging with 2.2μm pixels. That puts it in the sweet spot for compact machine vision and embedded vision sensors where 5MP is enough detail and geometry still matters. If you care more about measurement consistency than about making straight lines look perfect, this lens is the right kind of wide.

The construction is all glass in an aluminum housing, and that matters in systems that see real temperature swing. Plastic-heavy wide-angles often move more with heat, while this stack holds focus and alignment more consistently. The lens still weighs only 8g, so it fits normal board-level cameras without turning into a bulky mechanical problem.

The standard variant is rated IP67+. That makes it a good match for external-facing cameras exposed to rain, dust, or washdown splash. If you need a wide lens with controlled angular distortion and a rugged mechanical package, the CIL924 is the job-specific answer.
