Tungsten Filaments for Electron Microscopes

Loop and Pointed Filaments

Filament assemblies built by Energy Beam Sciences are the standard of the industry. With our assembly, whether standard or custom made, you can be assured of superior design and craftsmanship because we employ the most recent advances in ceramic and metallurgical technologies. We built our reputation creating filament tip styles which are uniquely suited to each application. They enhance electron beam instrument capabilities by providing a minute, intense, coherent beam emission that improves resolution and contrast.

Exclusive Features:

  • Rigid attachment of filament wire to posts with no possibility of waving due to mechanical instability
  • Minimum tip radius for coherent beam
  • Polished post ends
  • Precise dimensioning
  • Bases can be cleaned and rebuilt many times.
  • Better long term economy.
  • Available with standard loop, pointed or experimental filaments.
Prototype Filament Development

In addition to our standard range of filament assemblies, apertures and electron beam accessories, Energy Beam Sciences can provide complete product evaluation, engineering and manufacturing to customers with unique design requirements.
