Sony IMX546 · 8.1MP 1/1.8" global-shutter CMOS image sensor
IMX546 Sensor Specifications & Compatible M12 and C-Mount Lenses
IMX546 is a Sony 1/1.8-inch global-shutter CMOS image sensor from the Pregius S machine-vision family. Its near-square 2840x2840 (8.1MP) array on 2.74um pixels runs at 121 fps over SLVS-EC for high-speed inspection. Commonlands matches M12 Lenses to its 11.00mm image circle and reports the calculated horizontal, vertical, and diagonal field of view for each pairing.

Compatible Commonlands Lenses for the IMX546 with Calculated Field of View
Each field of view below is calculated for the IMX546 active area (7.78 × 7.78 mm) from Commonlands’ per-lens field-of-view data, which reflects each lens’s real distortion rather than a focal-length-only estimate. Alongside the horizontal, vertical, and diagonal field of view, each row lists the lens aperture (F#), distortion, ingress protection, total track length (TTL), and rated resolution, so you can shortlist on optics and mechanics in one pass. Coverage shows whether the lens image circle covers the 11.0 mm sensor diagonal. Only lenses that cover the full diagonal are listed. Run exact working-distance and object-size numbers through the field of view calculator.
Engineering picks for the IMX546
- Best ~30° HFoV: 16mm C-Mount Lens (CIL553) (16 mm, f/2.8). Why: the closest covering option to 30° horizontal, chosen for tight inspection framing and long read ranges. Field of view on the IMX546: 27° H × 27° V (38° diagonal); image circle covers the full sensor; verified 2026-07-02.
- Best ~60° HFoV: 8mm C-Mount Lens (CIL521) (8 mm, f/1.5). Why: the closest covering option to 60° horizontal, chosen for general-purpose machine-vision framing. Field of view on the IMX546: 52° H × 52° V (69° diagonal); image circle covers the full sensor; verified 2026-07-02.
- Widest covering option: 4.9mm C-Mount Lens (CIL505) (4.9 mm, f/2.2). Why: the widest horizontal field of view that still covers the full sensor. Field of view on the IMX546: 93° H × 93° V (135° diagonal); image circle covers the full sensor; verified 2026-07-02.
Commonlands offers 11 lens options for the IMX546: M12 Lenses and C-Mount Lenses from 2.7 mm to 75 mm focal length, spanning 6° to 183° horizontal field of view on the IMX546 active area.

covers means the lens image circle is at least as large as the 11.0 mm sensor diagonal, so the corners are not cropped. Need a focal length or coverage that is not listed here? Ask our engineers to confirm a match.
How to choose a lens for the IMX546
Start from the field of view your application needs, then read across to the focal length that produces it on the IMX546. Confirm the lens image circle covers the 11.0 mm diagonal so the corners are not cropped, and check the lens resolution is rated for 8.1 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.
