Frequently asked questions
What sensors work with the CIL231 3mm fisheye M12 lens?
The CIL231 covers 1/1.8 inch sensors including the Sony IMX728 and ON Semiconductor AR0823. It resolves 12MP+ at 1.55μm pixel pitch across a 9.0mm image circle.
What is the field of view of the CIL231 fisheye lens?
The CIL231 gives 190° field of view at the 9.1mm image circle. Use field of view calculator if you want the exact coverage on your sensor format.
Is the CIL231 IP67 waterproof?
Yes, the M12A variant of the CIL231 is IP67 sealed with a metal cap and barrel. It is rated for dust ingress and water immersion.
What is the distortion type on the CIL231 fisheye lens?
The CIL231 uses -10% F-theta distortion. That projection spreads angular resolution more evenly across the frame than an equidistant fisheye, which helps panoramic stitching and surround-view work.
Which M12 lens holders are compatible with the CIL231?
The Commonlands CLA019-LCP holder (8-13mm standoff) is one compatible mounting option. The lens also fits standard M12x0.5 mounts from e-con Systems, Allied Vision, FLIR, iDS, The Imaging Source, and Basler.
Does the CIL231 3mm M12 fisheye lens ship same day from the US?
Yes, in-stock CIL231 lenses ship same day from San Diego, California for orders placed before 12 PM PST. Over 60 units of each CIL231 variant are currently in stock.
