CMOS Image Sensors Featuring Enhanced Near Infra-Red Technology Improves Night Vision

Posted Apr 13, 2018 by ON Semiconductor

ON Semiconductor has introduced new CMOS image sensors, the AR0522 and the AR0431, featuring its the Near Infra-Red+ (NIR+) technology. The NIR+ technology effectively combines High Dynamic Range (HDR) with enhanced low light performance to enable high-end security and surveillance cameras.

The new AR0522 is a 1/2.5-inch 5.1 Megapixel (MP) image sensor based on a 2.2 micrometer (μm) Back Side Illuminated (BSI) pixel technology platform, developed for industrial applications that require high resolution, high quality video capture in low light conditions. The image sensor delivers approximately twice the sensitivity in the near Infra-Red wavelength of the existing AR0521 image sensor.

The AR0431 is a 1/3.2-inch 4 MP sensor based on a 2.0 μm BSI pixel technology platform. Offering versatile low power modes and a frame rate of up to 120 fps, it is perfect for applications where slow motion video capture is required. Its low operating power makes it ideal for battery-powered security cameras, as well as action/sports cameras, in-car DVRs and general surveillance cameras.

ON Semiconductor has developed NIR+ technology to increase the Quantum Efficiency (QE) of the sensors in the near Infra-Red region without sacrificing color fidelity in the visible spectrum. Through this technique, security cameras can use fewer IR LEDs on BOM driven at lower voltages and still achieve high quality images in low light and NIR conditions.

The AR0522 engineering samples are available in a 12 mm X 12 mm mPLCC package, with mass production planned for May 2018. Engineering samples of the AR0431 will be available later in April 2018 in a 10 mm x 10 mm mPLCC package, with mass production starting in July 2018.
