- There are two types of electron microscopes ; that is Scanning Electron Microscope and Transmission Electron Microscope.
- Transmission electron microscope are used for studying internal structures of cells. In these microscopes electromagnets are used to magnify the image by passing a beam of electrons through a thin specimen.
