AR0521 sensor specifications and
compatible M12 lenses & C-mount lenses
The AR0521 from onsemi is a 1/2.5-inch rolling-shutter CMOS image sensor for industrial and embedded imaging. It produces 2592x1944 (5.0 MP) at 48 fps using 2.2um pixels across a 7.13mm diagonal, with HiSPi, MIPI CSI-2, or parallel output in color or mono. Commonlands matches M12 Lenses to this image circle and reports the calculated horizontal, vertical, and diagonal field of view for each match.

Compatible Commonlands lenses for the AR0521. Field of View calculated with Distortion.
Each field of view below is calculated for the AR0521 active area (5.7 × 4.28 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 7.13 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 AR0521
Start from the field of view your application needs, then read across to the focal length that produces it on the AR0521. Confirm the lens image circle covers the 7.13 mm diagonal so the corners are not cropped, and check the lens resolution is rated for 5.0 MP or higher so it resolves the 2.2 µm pixels. For exact working-distance and object-size numbers, run the figures through the Commonlands field of view calculator.
Sourcing a MIPI camera module around the AR0521? Commonlands can provide customized MIPI modules with our lenses; MoQs apply. Commonlands provides M12 lenses and C-mount optics and ships from San Diego, with same-day shipping for in-stock lenses ordered by 12 PM PST. We also assemble and align lens-to-sensor modules.
