The lens can resolve nanoscale features separated by distances smaller than the wavelength of light. It uses an ultrathin array of tiny waveguides, known as a metasurface, which bends light as it passes through, similar to a curved lens.<\/p>\n<p><!-- Link: <a href=\"http:\/\/phys.org\/news\/2016-06-meta-lens-visible-spectrum-smaller-wavelength.html\">http:\/\/phys.org\/news\/2016&#45;06-meta-lens-visible-spectrum-...ength.html<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Curved lenses, like those in cameras or telescopes, are stacked in order to reduce distortions and resolve a clear image.
