As the beam scans the specimen in a raster pattern, it excites the atoms in the material, causing the emission of secondary electrons. This environment is necessary because air molecules would scatter the electron beam.
Observing Bacterial Morphology with Scanning Electron Microscopy
The result is a magnification power that can reach hundreds of thousands of times, revealing a universe of texture and structure far beyond the capabilities of optical instruments. An electron gun generates a beam that is precisely focused by electromagnetic lenses onto the surface of the sample.
For instance, fracture surface analysis allows scientists to distinguish between ductile and brittle failure modes. Manufacturers rely on SEM to perform failure analysis on defective chips.
