OmniVision OG05B20 · 5.0MP 1/2.5" global-shutter CMOS image sensor
OG05B20 Sensor Specifications & Compatible M12 and C-Mount Lenses
OG05B20 is an OmniVision 1/2.5-inch global-shutter CMOS image sensor from the PureCel Plus-S family, suited to barcode reading, gesture, and machine vision that needs distortion-free capture of moving subjects. It resolves 2592x1944 (5MP) on 2.2um pixels with NIR sensitivity at 60 fps over MIPI CSI-2 or DVP. Commonlands matches M12 Lenses and C-Mount Lenses to its 7.13mm image circle and provides the calculated horizontal, vertical, and diagonal field of view.

Lens selection for the OG05B20 with calculated field of view
Each field of view below is calculated for the OG05B20 active area (5.7 × 4.28 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 7.13 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 OG05B20
- Best ~30° HFoV: Telephoto 10.4mm M12 Lens (CIL104) (10.4 mm, f/3.8). Why: the closest covering option to 30° horizontal, chosen for tight inspection framing and long read ranges. Field of view on the OG05B20: 31° H × 23° V (38° diagonal). The image circle covers the full sensor (verified 2026-07-02).
- Best ~60° HFoV: Low Distortion 5.2mm M12 Lens (CIL052) (5.2 mm, f/3.4). Why: the closest covering option to 60° horizontal, chosen for general-purpose machine-vision framing. Field of view on the OG05B20: 58° H × 45° V (69° diagonal). The image circle covers the full sensor (verified 2026-07-02).
- Best ~120° HFoV: Low Distortion 1.8mm M12 Lens (CIL018) (1.8 mm, f/2.8). Why: the closest covering option to 120° horizontal, chosen for wide navigation and room-scale coverage. Field of view on the OG05B20: 120° H × 103° V (133° 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 OG05B20: 66° H × 52° V (78° 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 OG05B20: 39° H × 30° V (48° diagonal). The image circle covers the full sensor (verified 2026-07-02).
Every covering option below comes from the M12 Lens collection or the C-Mount Lens collection, from 1.5 mm to 100 mm focal length, spanning 3° to 190° horizontal field of view on the OG05B20.
Covers in the table means the lens image circle is at least as large as the 7.13 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 OG05B20
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 2.2 µm pixel pitch. Estimate framing with the Commonlands field of view calculator.
