Electron Microscopy

•  Electron microscopes have a much higher resolution than light microscopes

Electron microscopes use electron beams focused by electromagnets to magnify and resolve microscopic specimens

  • Transmission electron microscopes (TEM) generate high resolution cross-sections of objects
  • Scanning electron microscopes (SEM) display enhanced depth to map the surface of objects in 3D

Electron microscopes have two key advantages when compared to light microscopes:

  • They have a much higher range of magnification (can detect smaller structures)
  • They have a much higher resolution (can provide clearer and more detailed images)

Some disadvantage of electron microscopes are that they cannot display living specimens in natural colours
