AR2020 sensor specifications and
compatible M12 lenses & C-mount lenses
The AR2020 is an onsemi 1/1.8-inch rolling-shutter CMOS image sensor in the Hyperlux LP family, built for LED-flicker-free automotive and ADAS imaging. It resolves 5120x3840 (19.7 MP) on 1.4 um pixels across an 8.96 mm diagonal at up to 60 fps over MIPI CSI-2, in color or mono with NIR sensitivity. Commonlands matches M12 Lenses to the AR2020 image circle and reports the calculated horizontal, vertical, and diagonal field of view.

Compatible Commonlands lenses for the AR2020. Field of View calculated with Distortion.
Each field of view below is calculated for the AR2020 active area (7.17 × 5.38 mm) using our MCP server and Field of view calculator. The rectilinear formula FoV = 2 × arctan(dimension ÷ (2 × focal length)) is incorrect for many lenses as it doesn't include distortion. Coverage shows whether the lens image circle covers the 8.96 mm sensor diagonal. Fisheye and f-theta lenses do not follow the rectilinear formula, so their entries link to the product page for the mapped field of view.

Coverage key: covers = lens image circle ≥ sensor diagonal; crops = image circle smaller than the diagonal (expect vignetting at the corners); verify = image circle not published for this lens — ask our engineers to confirm coverage.
How to choose a lens for the AR2020
Start from the field of view your application needs, then read across to the focal length that produces it on the AR2020. Confirm the lens image circle covers the 8.96 mm diagonal so the corners are not cropped, and check the lens resolution is rated for 19.7 MP or higher so it resolves the 1.4 µm pixels. For exact working-distance and object-size numbers, run the figures through the Commonlands field of view calculator.
