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 ...

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 ...

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 ...

In the future, camera lenses could be thousands of times thinner and significantly less resource-intensive to manufacture. Researchers from Chalmers University of Technology, Sweden, now present a new ...

To take high-quality images of the stars, astronomers usually need thick, curved lenses to bend the light precisely. But researchers have designed a flat lens that can take sharp images of the night ...

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 ...

Credit card-thick, flat lenses with tunable features based on graphene and gold have been developed by a partnership of Korean- and UK-based researchers. They say that such optical devices “could ...
