OmniVision Technologies, Inc., a developer of advanced digital imaging solutions, today introduced Nyxel, a near-infrared (NIR) technology that leverages novel silicon semiconductor architectures and processes to tackle challenges that plague existing approaches to NIR detection in image sensors. The result is an increase in quantum efficiency (QE), of up to 3x at 850nm and 5x at 940nm, when compared with our legacy NIR-capable sensors. These improvements in NIR sensitivity enable the image sensor to see better and farther under the same amount of light, extending the image detection range. Conversely, to match the performance of existing systems, Nyxel technology-based camera systems require fewer LED lights, thus reducing overall power consumption. Due to these benefits, Nyxel technology is well-suited for a wide variety of applications, including: surveillance, machine-vision, and automotive applications.
Features include:
- NIT technology allows for higher-resolution image capture with fewer power-hungry LEDs than technology using the visibile light spectrum
- Addresses the stringent requirements of next-generation mobile and AR/VR products with machine-vision applications
- Also suitable for automotive and security camera applications that require high NIR sensitivity
- Combines thick-silicon pixel architectures with careful management of wafer surface texture to improve QE, and extended DTI to help retain MTF without affecting the sensor’s dark current
- A 3x QE improvement for 850nm sensitivity and a 5x QE improvement for 940nm sensitivity when compared with OmniVision’s legacy NIR capabilities
