Researchers have demonstrated the first planar lens that works with high efficiency within the visible spectrum of light — covering the whole range of colors from red to blue. The lens can resolve nanoscale features separated by distances smaller than the wavelength of light. It uses an ultra-thin array of tiny waveguides, known as a metasurface, which bends light as it passes through.
