Optical Coating Laboratory

Organizational Unit

The Optical Coating Laboratory depends on the Department of Optics and is purpose is the production of thin films deposits onto optical surfaces with multiple uses: mirrors, anti-reflective films, interference filters, etc. The equipment consists mainly of a Balzers BAK 600 evaporator machine with a built-in electron gun that allows working with materials of high melting temperature. It is also equipped with a setup of multiple quartz crystals for monitoring the deposition thickness. The room occupied by the evaporator machine inside the laboratory is a class 7 clean room. In addition, the laboratory has a fume hood for gas extraction to avoid its inhalation during the cleaning processes.
