Electron beam evaporation system for security application

Building on more than 35 years of experience of electron beam and sputtering web coating, the TopBeam™ 1100S system combines the advantages of both process worlds:

  • Electron beam evaporation offers the highest coating speed of all vacuum coating processes. Oxide coating speeds can be a factor of 100 to several thousand times higher compared to sputtering. For precise coating thickness uniformity, a closed-loop inline control system such as ESCOSYS™ is mandatory. This monitors both the transverse and machine direction and is operated with an appropriate in-line measurement system. A wide variety of different metals and oxides can be evaporated using electron beam when utilizing the optimized type and shape of the evaporation crucibles.
  • Sputtering processes offer an even greater variety of coating materials and for metallic sputtering processes, the transverse coating thickness uniformity is inherent.

The TopBeam™ 1100S system is the optimum solution for layer stacks consisting of thick oxide layers and thin metal layers. The coating speeds for the single layers can be fitted to each other and both layers can be produced with single-pass coating. For other cases, or for more complex layer stacks, the reversible winding system can be used.
