WebScanning Electron Microscopes work pretty much the same way that optical microscopes do. In an optical microscope, light is emitted onto a sample. That light reflects from the sample and is captured, focused, and magnified by lenses. Optical Microscope (left) vs Scanning Electron Microscope (right). Webof the microscope by heating of a metallic filament. The electron beam follows a vertical path through the column of the microscope. It makes its way through electromagnetic lenses which focus and direct the beam down towards the sample. Once it hits the sample, other electrons (backscattered or secondary) are ejected from the sample.
