onsemi AR0341 · 2.9MP 1/3.6" rolling-shutter CMOS image sensor
AR0341 Sensor Specifications & Compatible M12 and C-Mount Lenses
AR0341 is an onsemi 1/3.6" rolling-shutter CMOS image sensor from the Hyperlux AT family, targeting automotive ADAS imaging. It resolves 1920x1536 (2.9 MP) on 2.1 um pixels across a 5.16mm diagonal at up to 60 fps over MIPI CSI-2, in color. Commonlands matches M12 Lenses to its 5.16mm image circle and calculates the horizontal, vertical, and diagonal field of view for each candidate lens.

Lens selection for the AR0341 with calculated field of view
Each field of view below is calculated for the AR0341 active area (4.03 × 3.23 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 5.16 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 AR0341
- Best ~30° HFoV: 7.2mm M12 Lens (CIL872) (7.2 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 AR0341: 32° H × 25° V (40° diagonal). The image circle covers the full sensor (verified 2026-07-02).
- Best ~60° HFoV: Wide-Angle 3.9mm M12 Lens (CIL339) (3.9 mm, f/1.6). Why: the closest covering option to 60° horizontal, chosen for general-purpose machine-vision framing. Field of view on the AR0341: 60° H × 48° V (76° diagonal). The image circle covers the full sensor (verified 2026-07-02).
- Best ~120° HFoV: Fisheye 1.95mm M12 Lens (CIL281) (1.95 mm, f/1.8). Why: the closest covering option to 120° horizontal, chosen for wide navigation and room-scale coverage. Field of view on the AR0341: 119° H × 95° V (153° diagonal). The image circle covers the full sensor (verified 2026-07-02).
- Lowest distortion: Low Distortion 4.4mm M12 Lens (CIL043) (4.4 mm, f/3.2). Why: measured -0.5% TV distortion, the flattest image among covering lenses. Field of view on the AR0341: 49° H × 40° V (61° diagonal). The image circle covers the full sensor (verified 2026-07-02).
- Best low light: 8mm C-Mount Lens (CIL521) (8 mm, f/1.5). Why: the fastest covering aperture (f/1.5), which collects the most light per pixel. Field of view on the AR0341: 28° H × 23° V (36° diagonal). The image circle covers the full sensor (verified 2026-07-02).
Find a lens for the AR0341 in the M12 Lens collection or the C-Mount Lens collection. The covering options below run from 0.8 mm to 100 mm focal length and span 2° to 226° horizontal field of view on the AR0341 active area.
Covers in the table means the lens image circle is at least as large as the 5.16 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 AR0341
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 2.1 µm pixel pitch. Estimate framing with the Commonlands field of view calculator.
