Answer;
Electron microscope
Explanation;
-Electron microscopes focuses beams of electrons on specimens, they produce images by focusing beams of electrons.
-They utilize the same principles behind an optical microscope, but rather than photons or particles of light, concentrate electrons, charged particles located on the outside of atoms, onto an object.
-They focus the electron beam using electromagnetic coils instead of glass lenses (as a light microscope does) because electrons can't pass through glass. There are two types of electron microscope; scanning electron microscopes (SEM) and transmission electron microscopes (TEM).
