WebOct 3, 2024 · In electron microscopes, electrons take over this job and collect data about the composition and structure of the specimen to produce the final magnified image. Electron microscopes can handle a much higher magnification level than other light microscopes. How a scanning electron microscope (SEM) works A scanning electron microscope scans a beam of electrons over a specimen to produce a magnified image of an object. That's completely different from a TEM, where the beam of electrons goes right through the specimen. Electrons are fired into the machine.
