Does an electron microscope have advantages over a light microscope?

Yes. An electron microscope (EM) uses a short-wavelength electron beam instead of visible light, so it can achieve far higher magnification and resolution than a conventional light microscope.

Biology LibreTexts notes that most light microscopes magnify only about 1,000× (sometimes up to ~1,500×), while an EM can produce sharp images magnified up to 100,000× or more and resolve subcellular and even some molecular structures. The trade-off is that electron microscopy generally cannot image living specimens because of vacuum and specimen-preparation requirements.
