The purpose of optical coatings is to change the reflectivity of optical surfaces. According to the materials and physical phenomena which are used one can in principle distinguish metallic and ...

Optical Surfaces Ltd. has announced investment in a coating facility that will allow the company, in future, to provide all standard metal coatings on mirror substrates up to 355mm in diameter.

For more than a century, optical coatings have been used to better reflect certain wavelengths of light from lenses and other devices or, conversely, to better transmit certain wavelengths through ...

Gravitational wave detectors rely on exquisitely sensitive optical systems, where mirror coatings play a critical role. In these systems, coating thermal noise – originating from intrinsic mechanical ...
