comparison of light and electron microscopes

  1. 1. Comparing Light and Electron MicroscopesAdvantages of Electron Disadvantages of Light Microscopes Microscope• Greater magnification up • Magnification only up to to 1,000,000 x 1000-1,500 x• Greater depth of field • Less depth of field (With SEMs, 3-D ) • May involve complex• No complex lighting lighting requirements• Greater resolution -1 nm • Less resolution - 1 micron
