Thin film coatings
Bte Bedampfungstechnik GmbH coats glass, metal and plastic with optical function layers. For this purpose metals (gold, silver, aluminium) or so-called dielectrics are vaporized in high vacuum.
In order to ensure a correct vaporization process, it is important to control and manage the pressure in the fore-vacuum chamber and the pressure in the high vacuum chamber. Only if the pressure is in the defined range, a good quality of the vaporized products can be guaranteed.
In order to control the vacuum a VSH88D (Pirani/hot cathode) and a VSP63MV (Pirani, analogue) vacuum transducer are used. These vacuum gauges control and manage the functionality of the fore and high vacuum pumping station, control and regulate the gas dosing, it necessary for a process.
A core competence of the Bte Bedampfungstechnik GmbH is coating of optical components for technical applications. Bte trusts in vacuum instruments of Thyracont for many years.
