A new type of flat, ultrathin lens designed to be free of chromatic aberrations has been developed by researchers in the US. The device has a variety of potential applications, from ultralight imaging ...

Ultra-thin flat lenses suitable for photography are one step closer after a team of researchers at Harvard University made a major leap forward with its prototype wafer-thin flat lens. The new lens ...

Light of different colors travels at different speeds in different materials and structures. This is why we see white light split into its constituent colors after refracting through a prism, a ...

Researchers from Chalmers University of Technology in Sweden have demonstrated technology that could make it possible to produce ultra-thin camera lenses made from artificial materials known as ...

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 ...

Light of different wavelengths travels at different speeds in different materials and structures. But an ordinary lens cannot focus light of different wavelengths to a single spot due to dispersion ...

Astronomers have discovered more than 5,000 planets outside of the solar system to date. The grand question is whether any of these planets are home to life. To find the answer, astronomers will ...

Camera lenses could be going on a substantial diet, thanks to a new “metamaterial lens” developed by a team at Harvard University. Federico Capasso, a professor of applied physics and electrical ...
