A breakthrough in lens technology appears to be on the verge of revolutionizing optics. At just 2mm across and far thinner than a human hair, the tiny flat lens device can magnify nanoscale objects while giving a sharper focus than top-end microscope lenses. Unlike the curved disks of glass from cameras and binoculars, the flat lens is made of a thin layer of transparent quartz coated in millions of microscopic pillars. This new lens technology is thought to have several target markets including cell phone cameras, mass-produced cameras for quality control in factories, light-weight optics for virtual-reality headsets, and even contact lenses.
