Researchers develop a mass-producible, centimeter-scale metalens for VR, imaging

Metalenses—flat surfaces that use nanostructures to focus light—are poised to revolutionize everything from microscopy to cameras, sensors, and displays. But so far, most of the lenses have been about the size of a piece of glitter. While lenses this size work well for some applications, a larger lens is needed for low-light conditions, such as an imaging system onboard orbital satellites, and VR applications, where the lens needs to be larger than a pupil.
