With the increasing number of advanced imaging tools available, the utility of conventional imaging techniques is often overlooked. an electron beam because electrons will quickly disperse or scatter due to collisions with other molecules. For topographic imaging, a focused beam of 0.1 to 50 keV electrons is scanned over the specimen and a detected secondary electron signal is used to form a facimile image of the Share. Scanning Electron Microscopy (SEM) is a test process that scans a sample with an electron beam to produce a magnified image for analysis. The method is also known as SEM analysis and SEM microscopy, and is used very effectively in microanalysis and failure analysis of solid inorganic materials. 3. References .
