Frequently asked questions

What sensor format is CIL324 designed for?

CIL324 is specified for 1/2.5″ sensors and uses a 7.25mm image circle. That format lines up with moderate-resolution wide-angle camera modules.

Is CIL324 a good fit for low-light imaging?

Yes, within the limits of its resolution class. The F/1.9 aperture is fast for a fisheye and helps preserve exposure time and frame rate in dim scenes.

What does the IP69K option mean on CIL324?

The IP69K option means the M12B version is sealed for harsh environments, including dust and high-pressure water exposure. That matters when the lens sits on the outside of a vehicle or machine.

How much distortion does CIL324 have?

The lens is specified at -14% F-Theta distortion. That is normal for a fisheye tuned for maximum coverage instead of straight-line preservation.

Does CIL324 include an IR cut filter?

Yes. The product data lists a 650nm IR cut, so this configuration targets visible imaging rather than deep near-IR transmission.

What resolution range is CIL324 intended to support?

CIL324 is rated for 2-3MP sensors. It is not the right choice if your main goal is pairing with a newer high-density 5MP small-format sensor.

CIL324 is a 2.4mm F/1.9 M12 fisheye lens for systems that need full hemispheric-style coverage from a compact board camera. It gives 180° field of view with -14% F-Theta distortion, which is the right trade when maximum scene coverage matters more than preserving straight lines.

The lens is built around a 7.25mm image circle and is specified for 1/2.5" sensors. Resolution is listed at 2-3MP, so this is not the lens to pair with a newer high-density 5MP small-format sensor. It makes more sense when you care about wide coverage, lower-light performance, and moderate pixel pitch instead of chasing raw resolution.

The optical stack is all glass in an aluminum housing, and the lens weighs 7.4g. The 650nm IR cut config targets visible-light imaging where color fidelity matters more than near-IR transmission. The fast F/1.9 aperture also helps preserve exposure time and frame rate in dim scenes.

A standard version and a sealed version are available, and the M12B variant is rated IP69K. That makes the CIL324 a good fit for external vehicle cameras, industrial equipment, and other installations that need washdown-level sealing with a very wide field.
