  • Invented 1600s
  • Microscopes more powerful today, work mostly same 
  • Pass light through glass lenses to magnify
  • Powerful models about 2000x magnification
  • Often stain cells- see organelles clearly
  • More magnification = better
  • Resolution = amount of detail- smallest distance between 2 points
  • Electron microscope more powerful 
  • Electron microscopes- no light or lenses- pass beam of electrons through sample
  • ^Then detect how many electrons pass through sample to get image
  • Can see structures of organelles (nucleus etc)- electron 
  • Magnification = image size / real size 
  • Millimetre standard form: 1x10-3
  • Micrometre…
