Flat lens opens a broad world of color

10-Feb-2017

Last summer, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) announced a new, flat lens that could focus light with high efficiency within the visible spectrum. The lens used an ultrathin array of nanopillars to bend and focus light as it passed. The ...
