Mini-Coater - high vacuum coating system

for thin film deposition

Mini-Coater Versions

2 Evaporation Boat Version

New general purpose high-vacuum coating system.  Modular system to be configured according to vacuum coating application e.g. with thermal evaporation and electron beam evaporation. Extremely simple to use and with short cycle times (air-vacuum-air), this system is ideal for rapid vacuum prototyping and small scale thin film deposition; an indispensible tool for academic and industrial, research and teaching laboratories.

The bell-jar configuration is extremely versatile and lends itself easily to applications such as coating by evaporation (thermal and e-beam), magnetron sputtering and plasma decomposition (RF, microwave and DC).  Plasma options may also be used for etching and plasma study / demonstration.
