Easily measure the intensity of near-infrared light sources used for sensing applications, from facial and gesture recognition to eye tracking and LiDAR. The Radiant Vision Systems Near-Infrared (NIR) ...

For the first time, researchers have used ultra-thin layers of 2D structures known as metasurfaces to create holograms that can measure the polarization of light. The new metasurface holograms could ...

Ellipsometry is a non-destructive, optical measurement technique that characterizes the optical properties of thin films. It is highly sensitive to changes in the thickness and refractive index of the ...

Wide bandgap semiconductor materials are highly useful in power electronics due to their ability to work at high temperatures, power, and frequency. Gallium nitride (GaN) is a wide bandgap ...
