The next generation of large scale telescopes will need durable mirrors that are highly reflective, uniform and have substrate diameters in excess of 8 meters. Traditionally, evaporative coatings have ...

Engineers have found a way to make liquid metals switch between reflective surfaces or those that scatter light. The transition only requires a small zap of electricity and could be used to make ...

A high reflectivity mirror, also known as a supermirror, is a dielectric mirror that has been carefully designed to provide optimal reflectivity while minimizing any scatter and absorption effects.

Many optical systems include mirrors as a component. They are used to direct and focus light, combine wavelengths, and reject specific wavelengths in imaging and a host of other applications. Multiple ...
