Scanning Electron Microscope (SEM)

Examples of use:

Imaging of high vacuum stable

  • Metal surfaces
  • Plastic surfaces
  • Ceramic and glass surfaces
  • Powders
  • Biological samples
  • Polished surfaces
  • non-conductive surfaces after coating with carbon or metals or at very low excitation energies


Device configuration:

  • Electron source: Schottky field emitter
  • Detectors for imaging material contrast and topography contrast
  • Resolution up to 0.7 nm (depending on sample)
  • Preparation technique for non-conductive surfaces:
    • High-vacuum vapor deposition system for carbon vapor deposition
    • High-vacuum sputtering system for gold or platinum,
    • Critical point drying preparation technique (for biological samples and samples containing water)
