Our team uses the electron beam evaporation and thermal evaporation methods as physical vapor deposition. There are 3 Evatec box-type coating systems which are called EVO and 640 machines with piezo-crystal based layer thickness monitoring. One of the systems is equipped with optical broad band monitoring. In the EVO machines, an ion assistance system  can be used during evaporation to create denser plasma environment. With these systems, it is possible to perform high reflection mirror, anti-reflection, dielectric, dichroic, filter coatings and more.
