AR1223 Sensor Specifications & Compatible M12 and C-Mount Lenses
AR1223 is an onsemi 1/1.6" rolling-shutter CMOS image sensor from the Hyperlux LH family, designed for automotive imaging with NIR response. It delivers 4096x3046 (12.5 MP) on 2 um pixels across a 10.21mm diagonal at up to 60 fps over MIPI CSI-2, in color or mono. Commonlands matches M12 Lenses to its 10.21mm image circle and provides the calculated horizontal, vertical, and diagonal field of view.

Lens selection for the AR1223 with calculated field of view
Each field of view below is calculated for the AR1223 active area (8.19 × 6.09 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 10.21 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 AR1223
- 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 AR1223: 29° H × 22° V (35° diagonal). The 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 AR1223: 54° H × 42° V (65° diagonal). The image circle covers the full sensor (verified 2026-07-02).
- Best ~120° HFoV: Wide-Angle 4.5mm M12 Lens (CIL344A) (4.5 mm, f/2.7). Why: the closest covering option to 120° horizontal, chosen for wide navigation and room-scale coverage. Field of view on the AR1223: 106° H × 78° V (134° diagonal). The image circle covers the full sensor (verified 2026-07-02).
- Compact low-cost pick: Telephoto 50mm M12 Lens (CIL051) (50 mm, f/2.8). Why: the lowest-priced covering M12 barrel ($79). Field of view on the AR1223: 9° H × 7° V (12° diagonal). The image circle covers the full sensor (verified 2026-07-02).

Covers in the table means the lens image circle is at least as large as the 10.21 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 AR1223
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 2.0 µm pixel pitch. Estimate framing with the Commonlands field of view calculator.
