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.
