WebNov 14, 2024 · Electron microscopes use electrons for imaging in a similar way that light microscopes use visible light. Unlike transmission electron microscopes (TEMs), which detect electrons that pass through a very thin specimen, SEMs use the electrons that are reflected or knocked off the near-surface region of a sample to create an image. 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.
