IMX531 sensor specifications and
compatible M12 lenses & C-mount lenses
IMX531 is a Sony 1.1-inch global-shutter CMOS image sensor in the Pregius S global-shutter machine-vision family. Its square 4512x4512, 20.4 MP array uses 2.74 um pixels at 109 fps over SLVS-EC, in color or mono across a 17.48 mm diagonal. Commonlands matches M12 Lenses to its image circle and calculates the horizontal, vertical, and diagonal field of view for each focal length.

Compatible Commonlands lenses for the IMX531. Field of View calculated with Distortion.
Each field of view below is calculated for the IMX531 active area (12.36 × 12.36 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 17.48 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.
| Commonlands Lens | Focal Length | Mount | F# | Horizontal FoV | Vertical FoV | Diagonal FoV | Coverage |
|---|---|---|---|---|---|---|---|
| Fisheye 1.3mm M12 Lens (CIL293) | 1.3 mm | M12 | f/2.2 | 184° | 184° | 184° | Circular image |
| 8.5mm C-Mount Lens (CIL508) | 8.5 mm | C-mount | f/2.4 | 75° | 75° | 98° | Covers |
| 12mm C-Mount Lens (CIL552) | 12 mm | C-mount | f/2.8 | 55° | 55° | 72° | Covers |
| 16mm C-Mount Lens (CIL553) | 16 mm | C-mount | f/2.8 | 42° | 42° | 57° | Covers |
| 25mm C-Mount Lens (CIL554) | 25 mm | C-mount | f/2.6 | 28° | 28° | 39° | Covers |
| 35mm C-Mount Lens (CIL555) | 35 mm | C-mount | f/2.6 | 20° | 20° | 28° | Covers |
| 50mm C-Mount Lens (CIL556) | 50 mm | C-mount | f/2.8 | 14° | 14° | 20° | Covers |
| 75mm C-Mount Lens (CIL557) | 75 mm | C-mount | f/3 | 9° | 9° | 13° | Covers |
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 IMX531
Start from the field of view your application needs, then read across to the focal length that produces it on the IMX531. Confirm the lens image circle covers the 17.48 mm diagonal so the corners are not cropped, and check the lens resolution is rated for 20.4 MP or higher so it resolves the 2.74 µm pixels. For exact working-distance and object-size numbers, run the figures through the Commonlands field of view calculator.
