EB Source for Metal Film

EGL Series



EGL-103S electron beam evaporation source is designed to improve performance and reliability based on ULVAC's many years of technical experience and achievements.
This evaporation source has a direct-acting three-point switching hearth with a maximum input power of 6kW.
EGL-103S has three crucibles with a capacity of 10cc, which is suitable for experiments in ultrahigh vacuum and small-scale production.


  • Suitable for small-scale production in ultra-high vacuum due to the adoption of a direct-acting 3-point switching hearth with a capacity of 10cc.
  • By scanning the beam spot in the X-axis and Y-axis directions even with a sublimable substance, the partial digging phenomenon can be eliminated and the entire crucible can be evaporated smoothly.(Japan patents 831485, 843447)
  • The electron beam is deflected 270°, so it is not exposed to the above from the vaporized material and the filament has a long life.
  • Since the emitter assembly can be easily attached and detached, it is easy to replace the filament, insulator, etc.
