... Lynsey Mansfield 26th September 2002 Electron Microscopy The electron microscope is an intense microscope. It can see things that a normal microscope cannot. The electron microscope cannot be used to look at living cells. Increasing the magnification in electron microscopy results in an increase in the amount of visible detail. There is a vacuum inside an electron microscope. Photographs of specimens viewed with an electron microscope are called electronmicrographs. The electron microscope uses electromagnets to focus the image onto a fluorescent screen. Light areas on an electronmicrograph are produced when electrons have been able to pass through the specimen. Electrons must be able to pass through parts of the specimen. Molecules in the air interrupt the flow of electrons. Electron-dense areas scatter the electrons and produce dark areas on the electronmicrograph. Electron beams cannot pass through glass. Beams of electrons have a very short wavelength. Thin sections are mounted on copper grids, which provide
