Frequently asked questions

What sensor format does CIL924 support?

CIL924 is specified for sensor formats up to 1/2.5″ and uses a 6.4mm image circle. That is the format range it was built to cover.

What does +0.5% F-Theta distortion mean on this lens?

The +0.5% F-Theta spec means the lens stays very close to the intended F-Theta mapping at the 6.4mm image circle. In practice, that gives you more uniform angular behavior across the image than a conventional wide-angle lens.

Is CIL924 appropriate for outdoor camera placements?

Yes. The listed mechanical version is IP67+, so the lens is meant for cameras that may face dust, rain, and similar exposure.

Why does the all-glass, aluminum construction matter?

All-glass optics and an aluminum housing usually hold focus and alignment more consistently across temperature than lighter plastic-heavy designs. That matters in outdoor systems and cameras mounted near heat sources.

What resolution is CIL924 designed for?

CIL924 is rated for 5MP sensors with 2.2μm pixels. That is the resolution class where it lines up best.

How wide is the field of view on CIL924?

The CIL924 gives you a 156° field of view. That is wide enough for broad coverage without moving all the way to a full fisheye look.

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.
