Coating Materials
A large number of deposition techniques are used for the production of thin films for optical applications — the two most important categories are physical vapor deposition (PVD), namely thermal vaporization and sputtering, and chemical vapor deposition (CVD). It is obvious, that for each deposition technique suitable coating materials are required.
