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 ...

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.
