Meaning
An electron microscope is a type of microscope that can be used to create images of objects that are too small to be seen with a light microscope.
About Electron Microscopes
- An electron microscope cannot be used to view anything smaller than about 0.05 nanometres.
- Electron microscopes do not use Visible Light to image objects. Instead it uses a beam of electrons.
- Electron microscopes can be used to create images of objects as small as a single atom. This means they can be used to create images of atoms for physicists, molecules for chemists and viruses for biologists.
