OmniVision Technologies’ OS08A20 is the latest addition to its family of image sensors equipped with the Company's Nyxel near-infrared (NIR) technology. It is the first 8-Mpixel sensor to combine Nyxel technology with OmniVision's PureCel pixel architecture, which allows the sensor to capture high resolution video and images in all lighting conditions, making the OS08A20 a viable for professional surveillance systems.
Nyxel technology delivers significant quantum efficiency (QE) improvement at 850 nm and 940 nm while maintaining a high-modulation transfer function, allowing the OS08A20 to monitor a larger area compared with legacy technologies. Eliminating the need for external lighting sources reduces power consumption and enables covert surveillance for improved security. The OS08A20 is also a color CMOS image sensor, employing the PureCel pixel architecture with backside illumination to capture crisp, clear color images during the daytime.
The OS08A20 supports image sizes up to 3,840 x 2,160 (16:9 aspect ratio) to capture high-resolution video at 60 fps. It comes in a 2 µm x 2 µm pixel size and 1/2-inch optical format for improved sensitivity. This image sensor is currently sampling and is expected to start volume production in the second quarter of 2018. For further illuminations, peruse the
