A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

Diffraction gratings are beautiful things, bending transmitted and reflected light and splitting it into its component wavelengths to create attractive iridescent rainbow patterns. It’s the same ...

Reflective ruled diffraction grating is a kind of optical glass substrate composed of dense, equidistant parallel lines, and the surface is coated with aluminized, multi-layer dielectric or other ...
