Electron microscope components

Thermo Fisher Scientific is a world-leader in electron microscopy component products such as thermal field emission sources and liquid metal ion sources.


Electron emitters

Thermal field emission electron guns

Schottky emission, a form of thermal field emission, is the leading electron source technology used in our advanced electron beam equipment. The most common applications of Schottky emissions are seen in high resolution SEM, TEM, e-beam lithography, and Auger systems.

Advantages

  • Easy to use
  • Long source life
  • Small virtual source size
  • High brightness
  • High stability
  • Low noise

Focused ion beam sources

Liquid metal ion sources

Liquid metal ion sources (LMIS) are the answer to high resolution, focused ion beam (FIB) imaging, nanofabrication, depth profiling, SIMS*, ion doping and ion beam lithography. Thermo Fisher Scientific uses liquid metal ion sources in a variety of configurations: FIB columns, FIB systems, and DualBeam systems.

Advantages

  • High angular intensity
  • Stable emission process

Single crystal tungsten

We also offer zone refined single crystal tungsten wire in a myriad of orientations, diameters, and lengths.
