Scanning electron microscope

• Electrons focused using electromagnets
• Electrons deflected/bounce off specimen surface
• Generates a 3D image of surface
• High resolution due to short wavelength of electrons
• Can't see internal structures
• Specimen does not need to be thin
• High magnification (x1,000,000)
• Can only view dead/dehydrated specimens as uses a vacuum
• Complex preparation so artefacts often present
• Does not show colour
