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.

Researchers in Israel have made a new type of contact lens that can correct a form of red–green colour blindness known as deuteranomaly. By incorporating plasmonic metasurfaces into standard contact ...

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 ...
