For all the sophisticated technology humans have invented to capture images, the lenses we use on cameras still rely on 19th-century technology. All that could be about to change with the invention of ...

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 ...

In a lab in Zurich, scientists have built something that, at first glance, shouldn’t be possible. When a beam of infrared light strikes their ultra-thin lens—barely thicker than a red blood cell—it ...

AR and VR headsets of the future could have clearer, lighter, and wafer thin lenses, thanks to a new manufacturing process that uses nanotechnology to not only shrink the thickness of the lens, but ...

(Nanowerk News) Curved lenses, like those in cameras or telescopes, are stacked in order to reduce distortions and resolve a clear image. That's why high-power microscopes are so big and telephoto ...
