LEDs can shed infrared light on low cost, long lifetime sensors to monitor carbon dioxide levels in buildings, suggests Ralph Weir. To most people carbon dioxide (CO2) is a ‘greenhouse gas’, but not ...

Near-Infrared Sensor Technology Shines in Low/No-Light Conditions March 27, 2020 Process refinements result in near-infrared technology for image sensors that deliver 50% quantum efficiency for ...

As this technology enables weak light in the near-infrared region, whose detection and utilization are difficult even in sunlight, by converting it to visible light, it can significantly improve the ...
