Harvard researchers have made advancements in development of a flat lens known as a metalens - for the first time, it can work with a continuous range of colors rather than one at a time. Research has been ongoing at the University's School of Engineering and Applied Sciences, showing last summer that it was possible to create a lens 100,000x thinner than glass that could focus light in the visible spectrum. This metalens uses an array of titanium dioxide nanopillars to direct light, eliminating...
