Frequently asked questions
What sensors does the CIL093 2.8mm M12 lens support?
The CIL093 supports 1/2.5 inch sensors resolving 5MP at 2.2μm pixel pitch, including the Sony IMX577. Its 7.6mm image circle covers the full 1/2.5 inch diagonal.
Why does the CIL093 use molded glass aspheres?
The molded glass aspheres help the CIL093 hold focus more consistently across temperature than plastic elements do. That all-glass design stays stable from -20°C to 60°C, which matters in outdoor robots and surveillance cameras.
How much distortion does the CIL093 have?
The CIL093 has -3% TV distortion across the 7.6mm image circle. That is low for a 112 degree wide-angle lens, and many competing 2.8mm M12 lenses in this class run 5-10% barrel distortion instead.
Is the CIL093 NIR corrected for day/night cameras?
Yes. The CIL093 is NIR corrected, so visible and near-infrared wavelengths stay in focus together. You should order CIL093-F2.4-M12ANIR for day-night systems that use 850nm or 940nm IR illumination.
What cameras work with the CIL093 2.8mm M12 lens?
The CIL093 works with e-con Systems S-mount boards, Allied Vision Alvium, FLIR Blackfly S, iDS uEye LE, The Imaging Source M12, and Basler Dart cameras. The Commonlands CLA018 lens holder is the standard mount, and iDS uEye Rev1.2 needs the part number ending in C-NO.
Does the CIL093 ship same day from the US?
Yes. Orders placed before 12 PM PST ship the same day from our San Diego warehouse. Contact engineering@commonlands.com if you need volume pricing or MTF test data for the CIL093.
