microscopes

• 4 types of microscopes

  • Light
  • Laser scanning confocal
  • Transmission electrons microscope (TEM)
  • Scanning electrons microscopes (SEM)
• Light Microscope

  • Resolution : 0.2 micrometres
  • Magnification : x1500
• Laser Scanning Confocal Microscope

  • Fluorescent dye
  • Image can be 3D
  • Clearer image than light microscopes
  • View different depths in thick specimens
• Transmission Electrons Microscope (TEM)

  • Denser parts absorb more electrons - Darker
  • High resolution : 0.0002
  • Magnification : x1000000
• Scanning electrons microscopes (SEM)

  • Can be 3D
  • Lower resolution than TEMs
  • Magnification : x50000
