AR2020などの最大1/1.8型センサーに対応した低歪み5.2mm M12レンズ

CIL232 is a 3.1mm M12 fisheye lens with a 200° field of view for sensors up to 1/1.7" format. The lens uses an F/1.9 aperture, weighs 12g, and covers an 8.8mm image circle in a miniature IP67-sealed package. The all-glass aluminum barrel is athermalized, so temperature swings do not push focus around as much.

Distortion stays under 10% F-Theta, which is controlled for a lens this wide. On the IMX728 or AR0823, the lens resolves 12MP+ at 1.85µm pixel pitch across the full 181° at the 8.8mm image circle. That much angular coverage matters in surround-view systems, downward-facing drone cameras, and 360° stitching because blind spots cause more trouble than curved lines.

Commonlands offers CIL232-F1.9-M12A650 with a 650nm IRC for daylight imaging or CIL232-F1.9-M12ANIR without the filter for NIR-sensitive work. The M12A variant is IP67-sealed and uses BBAR coating on the first lens surface.

The lens is compatible with the Commonlands CLA019-LCP lens holder. It also works with e-con Systems boards (8–13mm tall mount), Allied Vision Alvium, FLIR Blackfly S, iDS uEye XLS, The Imaging Source, and Basler Dart S-mount cameras. You can use field of view calculator to model exact coverage on your sensor.

The lens ships same day from San Diego for orders before 12 PM PST. Trioptics MTF test data and mechanical drawings are available on request. You can try depth of field calculator for depth of field estimates at your target working distance.
