Harvard researchers have developed metalens, an electronic flat lens that works like the human eye. The technology used in the new artificial eye will revolutionize the lenses used in cameras, VR/AR headsets and eyewear. The special features of the lens include simultaneous focus, control of aberrations caused by astigmatisms and image shifts. The Lens demonstrates the feasibility of embedded optical zoom and autofocus for a wide range of applications, including cell phone cameras. It uses tiny nanostructures to focus light and hence the entire visible light spectrum at a single point.
