Sony IMX541 · 20.4MP 1.1" global-shutter CMOS image sensor
IMX541 Sensor Specifications & Compatible M12 and C-Mount Lenses
IMX541 is a Sony 1.1-inch global-shutter CMOS image sensor in the Pregius S machine-vision family, with a square 4512x4512 (20.4MP) array on 2.74um pixels running at 42 fps over SLVS-EC. Its symmetric format suits alignment and metrology applications. Its 17.48 mm image circle sits beyond M12 Lens coverage, so the C-Mount Lenses in the table below carry it, each with its calculated horizontal, vertical, and diagonal field of view.

Lens selection for the IMX541 with calculated field of view
Each field of view below is calculated for the IMX541 active area (12.36 × 12.36 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 focal length, mount, aperture (F#), and coverage. Follow the product links for distortion, ingress protection, dimensions, and resolution specifications. Coverage compares the lens image circle with the 17.48 mm sensor diagonal. Entries marked Circular image do not cover the full diagonal; part of the sensor lies outside the image circle. Run working-distance and object-size numbers through the field of view calculator.
Engineering picks for the IMX541
- Best ~30° HFoV: 25mm C-Mount Lens (CIL554) (25 mm, f/2.6). Why: the closest covering option to 30° horizontal, chosen for tight inspection framing and long read ranges. Field of view on the IMX541: 28° H × 28° V (39° diagonal). The image circle covers the full sensor (verified 2026-07-02).
- Best ~60° HFoV: 12mm C-Mount Lens (CIL552) (12 mm, f/2.8). Why: the closest covering option to 60° horizontal, chosen for general-purpose machine-vision framing. Field of view on the IMX541: 55° H × 55° V (72° diagonal). The image circle covers the full sensor (verified 2026-07-02).
- Best low light: 8.5mm C-Mount Lens (CIL508) (8.5 mm, f/2.4). Why: the fastest covering aperture (f/2.4), which collects the most light per pixel. Field of view on the IMX541: 75° H × 75° V (98° diagonal). The image circle covers the full sensor (verified 2026-07-02).
This larger format pairs with the C-Mount Lens collection. Covering lenses below run from 1.3 mm to 75 mm focal length and span 9° to 184° horizontal field of view on the IMX541 active area.
| Commonlands Lens | Focal Length | マウント | 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マウント | f/2.4 | 75° | 75° | 98° | Covers |
| 12mm C-Mount Lens (CIL552) | 12 mm | Cマウント | f/2.8 | 55° | 55° | 72° | Covers |
| 16mm C-Mount Lens (CIL553) | 16 mm | Cマウント | f/2.8 | 42° | 42° | 57° | Covers |
| 25mm C-Mount Lens (CIL554) | 25 mm | Cマウント | f/2.6 | 28° | 28° | 39° | Covers |
| 35mm C-Mount Lens (CIL555) | 35 mm | Cマウント | f/2.6 | 20° | 20° | 28° | Covers |
| 50mm C-Mount Lens (CIL556) | 50 mm | Cマウント | f/2.8 | 14° | 14° | 20° | Covers |
| 75mm C-Mount Lens (CIL557) | 75 mm | Cマウント | f/3 | 9° | 9° | 13° | Covers |
Covers in the table means the lens image circle is at least as large as the 17.48 mm sensor diagonal. Confirm corner illumination and MTF at your aperture, wavelength, and working distance. A complete circular fisheye image fits inside the sensor only when its diameter is no larger than the sensor's short side. 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 IMX541
Start from the field of view and working distance your application needs. Confirm that the lens image circle covers the active sensor diagonal and that the mount provides the required focus travel and rear clearance. A lens megapixel rating alone does not establish resolution on this sensor. Compare measured MTF at the spatial frequencies your task needs, at the intended aperture, wavelength, distance, and field position, accounting for the 2.74 µm pixel pitch. Estimate framing with the Commonlands field of view calculator.
