Engineers at the University of Utah have developed a new method of creating optics which are flat and ultra-thin, yet can still bend light to a single point like traditional lenses. It's hoped the ...

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light. Lenses are the most widely used ...

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 ...

Infrared light passes through the metal lens and is converted into violet light and focused in a focal point due to the material and the special surface structures—enlarged in the magnifying glass.
