Frequently asked questions

What does IR corrected mean on the CIL250 25mm M12 lens?

It stays in focus from visible wavelengths through 850nm near-infrared. A day/night camera using IR illumination at night does not need mechanical adjustment, which is the whole point of IR correction.

What sensors are compatible with the 25mm CIL250 S-mount lens?

The CIL250 fits 1/1.7 inch sensors up to 10MP, including the Sony IMX678, OmniVision OX05B1S, and similar sensors within the 9.4mm image circle.

Can the CIL250 25mm M12 lens be used for license plate recognition?

Yes. The 25mm focal length gives a 20-degree field of view that works for license plate recognition at 10 to 30 meters, depending on plate size and sensor resolution. IR correction also helps at night with 850nm illumination.

What is the difference between a standard M12 lens and an IR corrected M12 lens?

A standard M12 lens is optimized for visible light only. An IR corrected M12 lens keeps the focus point consistent from visible through 850nm NIR, which matters in day/night security cameras, agricultural NDVI imaging, and other NIR systems.

Does the CIL250 25mm M12 lens ship from the United States?

Yes. Commonlands ships all in-stock lenses same day from San Diego, California for orders placed before 12 PM PST.

Is volume pricing available for the CIL250?

Yes. Contact Commonlands for volume pricing on orders of 100 units or more. Production quantities ship with lot traceability and consistent lead times.

CIL250 is a 25mm IR corrected M12 lens for day/night imaging on 1/1.7" sensors up to 10MP. The IR correction holds the focus plane stable from visible light through 850nm near-infrared, so a camera that switches to NIR at night stays sharp without mechanical refocus.

The 20-degree horizontal field of view works for license plate recognition at 10 to 30 meters, perimeter monitoring, agricultural imaging, and RGBIR systems built around sensors such as the OX05B1S or IMX678. If you need reach from a small board camera, this is the use case.

The fixed F/2.0 aperture gives you reasonable light collection for a 25mm lens, and distortion stays below 3%. The 9.4mm image circle covers 1/1.7" cleanly. The 30mm total track length and 6g weight also keep the package small enough for embedded systems, UAV payloads, and multi-camera arrays.

The entrance pupil sits at 9.9mm, which reduces vignetting on cameras with recessed sensor windows. Many compact 25mm M12 lenses overlook that detail, and it usually shows up later as lost corner performance.

The CIL250 works with Commonlands CLA024 lens holders, FLIR Blackfly S, Allied Vision Alvium, Basler, and iDS board cameras. Orders placed before 12 PM PST ship from San Diego the same day.
