Omnivision adds three BSI GS sensors

Omnivision has introduced three new back-side illuminated (BSI) global shutter (GS) image sensors for machine-vision applications including industrial automation, robotics, logistics barcode scanners and intelligent transportation systems (ITS). The new BSI GS image sensors with a 3.45-micron (µm) BSI pixel size offers high performance in the areas of sensitivity, shutter efficiency and low-light performance.

The image sensors’ small 3.45-µm pixels achieve high shutter efficiency at 106 dB. With a 20Ke- full-well capacity (FWC), they deliver a higher high dynamic range (HDR) with low noise for clearer pictures. In addition, they incorporate the company’s proprietary technologies including an advanced PureCel Plus-S stacked-die architecture, Nyxel near-infrared (NIR) technology and on-chip dual conversion gain (DCG) HDR.

PureCel Plus-S enables thinner modules with best-in-class light absorption, enhanced image quality from higher sensitivity and a large angular response that prevents color shading issues, Omnivision said. The Nyxel NIR technology increases quantum efficiency (QE) at 700-1050 nm, which captures brighter images from farther away and DCG HDR extends dynamic range for motion artifact–free and low-noise images in challenging lighting conditions.

Thanks to their high performance with smaller pixels, these GS image sensors can replace larger 4.8-µm pixel front-side illuminated (FSI) sensors traditionally used in machine-vision products. Omnivision’s BSI GS sensor family features 3.45-µm and 2.2-µm pixel solutions with resolutions ranging from 2- to 9-megapixel (MP).

The three new BIS GS sensors include the following devices:

• The OG02C10/1B: 2-MP BSI GS sensor in a 1/2.53-inch optical format (OF) that supports 300 frames per second (fps)
• The OG03A10/1B: 3-MP BSI GS sensor in a 1/1.8-inch OF that supports 150 fps
• The OG05C10/1B: 5-MP BSI GS sensor in a 1/1.45-inch OF that supports 120 fps

These new GS sensors fit the standard C-mount lens and support both LVDS and MIPI interfaces. The 3.45-µm BSI GS sensor family also includes the OG09A10, a 9-MP BSI GS sensor in a 1-inch OF. The 2.2-µm BSI GS sensor family includes the OG05B1B, a 5-MP resolution sensor in a 1/2.53-inch OF, and the OG01H1B, a 1.5-MP resolution GS sensor in a 1/4.51-inch OF.

The OG03A10/1B and OG05C10/1B sensors are available for sampling now and are in mass production. The OG02C10/1B sensor will be available for sampling in the first quarter of 2025 and mass production in the second half of 2025.

Omnivision is showcasing the new BSI GS sensors at VISION 2024, Hall 10, Booth 10G82, October 8-10, 2024, at Messe Stuttgart, Germany.
