Technology Benefits

OMNIVISION's Nyxel® NIR technology enables image sensors that see better and farther in low light while consuming less power.

Capture Sharper, Brighter Images

Nyxel® NIR technology achieves up to 3x quantum efficiency improvements to capture sharp, bright images and deliver optimum image data. This enables accurate eye tracking and gesture control in AR/VR applications, or for detecting distracted or drowsy drivers in driver-monitoring systems.

Improved Night Vision

With significant increases in NIR sensitivity, Nyxel® technology offers better photon absorption compared with other NIR technologies. This means improved night vision, allowing security cameras and ADAS surround-view systems to capture brighter images from farther away.

Minimal Power Requirements

While current machine-vision and night-vision NIR solutions are augmented by power-intensive IR LEDs, sensors built on Nyxel® technology require minimal additional lighting—reducing system power needs and extending the life of battery-operated security cameras.

"The judging panel were impressed with OMNIVISION's development of their Nyxel technology. The pixel design significantly increases NIR sensitivity. The technology can significantly improve the performance of automotive camera systems, particularly in cabin monitoring. It is unusual to see such a significant step forward in image sensing."

Technology Features

Nyxel® technology features QE improvements that increase sensitivity to the near-infrared spectrum.

Thick Silicon

Thicker silicon increases the chance of photon absorption, offering higher QE and increased signal strength than thinner silicon.
Deep Trench Isolation

Deep trench isolation creates a barrier between the pixels to eliminate crosstalk and improve modular transfer function.
Absorption Structure

Using a carefully managed optical scattering layer prevents defects in the image’s dark area and lengthens the photon path.
