Different Types of Electron Microscopes
Electron microscope offers many advantages over the traditional microscopes. There are three different types of electron microscopes. They are the transmission electron microscope, the scanning electron microscope, and the scanning-tunneling electron microscope.
The transmission electron microscope transmits electrons through a small slice of a specimen in order for the image to be seen. These types of microscopes are great for seeing inside the cells.
Other types of the electron microscope are the scanning tunneling microscope and the scanning electron microscope. Both these microscopes allow for an in depth look at materials. The scanning microscope can actually allow scientists to view items in 3-D because of the excited atoms.
The tunneling microscope actually creates a tunneling current between the electrons on a specimen and the microscopes tip to make the image. These are very high tech microscopes.
