Scanning Electron Microscopy (SEM)


How Does It Work?
Where an optical microscope uses light to image a sample and delivers that light to either your eyes or a detector, a scanning electron microscope uses an electron beam to image a sample and uses a detector or variety of detectors to collect the information. An electron beam is generated from a filament and then focused using electromagnetic lenses into a fine beam as the electrons travel from their source to the sample.
When should it be used?
