Presentation Transcript


Compound light microscope

Compound Light Microscope

  • Uses twolenses and has a light source

  • Ocular lens usually magnifies x10

  • Can be used to view living cells

  • Highest magnification of a compound light microscope is 2,000x


Electron microscope

Electron Microscope

  • Beam of electrons produce an enlarged image of specimen

  • Highest magnification of an electron microscope is 200,000x

  • Cannot be used to view living cells


Scanning electron microscope

Scanning Electron Microscope

  • Electron beam is focused on a specimen coated with a very thin layer of metal

  • Electrons that bounce off form an image on a fluorescent screen

  • Show 3-D images of cell surfaces

  • Black and white images only (artificial colors sometimes added)


Transmission electron microscope

Transmission Electron Microscope

  • An electron beam is directed at a very thin slice of a specimen stained with metal ions

  • Electrons passing through the specimen strike a fluorescent screen, forming an image

  • The formed image can show the internal structure of a cell in fine detail

  • Black and white images only (artificial colors sometimes added)
