Harvard Metalens Research Could Impact AR/VR Applications

Researchers at Harvard University’s John A. Paulson School of Engineering and Applied Sciences (SEAS) made a breakthrough in metalenses, flat surfaces that focus light via nanostructures. Metalenses, which would replace curved lenses, have thus far been able to focus only on a limited spectrum of light, but SEAS engineers created a metalens that can focus, in high resolution, on the entire visible spectrum of light in the same spot. Previously, that effect could only be achieved by stacking many conventional lenses. Continue reading Harvard Metalens Research Could Impact AR/VR Applications
