Frequently asked questions

What sensors does the CIL219 fisheye M12 lens support?

The CIL219 fits 1/2.3 inch to 2/3 inch sensors including the ON Semiconductor AR1335 and Sony IMX677. It resolves 8-10MP at 2.2 micron pixel pitch across the 6.3mm image circle.

What is the field of view of the CIL219 fisheye lens?

The CIL219 gives a full 200° field of view at the 6.3mm image circle. That coverage is wide enough for surround-view, panoramic stitching, and ceiling-mounted surveillance with minimal blind spots.

Is the CIL219 weatherproof for outdoor use?

Yes. The CIL219 M12A variant is IP67 rated with a sealed metal barrel, so it is suitable for outdoor and washdown environments.

What type of distortion does the CIL219 fisheye lens have?

The CIL219 has -5% F-theta distortion, which makes it an equidistant fisheye. That mapping is useful because angular distance from the image center stays proportional to image distance.

What cameras are mechanically compatible with the CIL219?

The CIL219 works with e-con Systems standard S-mount boards using a 9-13mm tall holder, Allied Vision Alvium, FLIR Blackfly S, The Imaging Source M12, and Basler Dart cameras. iDS uEye LE Rev1.2 requires the part number ending in C-NO, and the Commonlands CLA018 holder is one compatible mount, and other options work as well.

Does the CIL219 M12 fisheye lens ship same day from the US?

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

The CIL219 is a 1.9mm M12 fisheye lens with a 200° field of view and a 6.3mm image circle. It covers sensors from 1/2.3 inch up to 2/3 inch formats including the AR1335 and IMX677, resolving 8-10MP at 2.2 micron pixel pitch. That amount of coverage is what you buy this lens for. It can see enough scene for panoramic stitching, surround-view, and ceiling-mounted surveillance without leaving obvious blind spots.

Distortion is -5% F-theta, which places the lens in the equidistant fisheye category. That projection keeps angular mapping predictable, so calibration and stitching behave more cleanly than they do with a generic ultra-wide lens that lacks a known mapping model. The two molded glass aspheric elements also keep edge sharpness better than you would expect from a compact fisheye in this price class.

The lens uses all-glass, all-metal construction and carries an IP67 seal. The metal barrel and cap include BBAR coating on the first surface to reduce ghosting, and the total weight stays at 13.3g, which is still manageable for drones, robots, and embedded vision builds. At F/2.5, the lens is not unusually fast, but it is fast enough for most wide-angle systems that can tolerate shorter exposure tradeoffs.

The M12A variant is available as CIL219-F2.5-M12A650 with a 650nm IR cut-off filter or as CIL219-F2.5-M12ANIR without a filter for NIR applications. The lens fits e-con Systems standard S-mount boards with a 9-13mm tall holder, Allied Vision Alvium, FLIR Blackfly S, iDS uEye LE, The Imaging Source, and Basler Dart cameras with the Commonlands CLA018 holder.

Commonlands ships in-stock parts same day from San Diego before 12 PM PST. You can contact the optical engineering team for volume pricing or custom filter options.
