Electron microscopy

Electrons have wavelike properties. Due to their high energy, electrons have a very short wavelength. This translates into much higher resolutions than what would be possible with light microscopes.

Types of electron microscopes:

  • Transmission Electron Microscopes (TEM) use a high voltage electron beam to produce an image, and the electrons that pass through the sample are detected.

  • Scanning Electron Microscopes (SEM) produce an image by probing the surface of a specimen.

  • Reflection electron microscopes (REM) use an electron beam that is pointed at a thin specimen to detect the scattered electrons that are reflected by the specimen.
