An electron microscope offers many things that other microscopes do not. For example, items that are placed on a microscope slide for electron microscopes are able to be seen with an amazing depth of field, since they can be magnified up to two million times their normal size. These are things that cannot be seen with a light microscope. One thing about electron microscopes is that they come in a variety of types that anyone can use if they are looking for a special type of microscope.
Three types of electron microscopes exist. They are the transmission electron microscope, the scanning electron microscope, and the scanning-tunneling electron microscope. The original of all of these types of microscopes is the transmission electron. The TEM, as it is commonly called, 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 of beings on the planet. Much has been learned by using these microscopes for seeing all types of various cells.
Two other types of the electron microscope exist. The scanning tunneling microscope and the scanning microscope are two very in depth types of microscopes that are used to view specimens. Both use atoms and electrons to view items, but the tunneling microscope creates a tunneling current between the tip of the microscope and the actual electrons in order to create an image. The scanning microscope can make a 3 D image that can make looking at cells and other minute items more simple and more in depth than ever experienced before.
The electron microscope can make viewing specimens so much easier than ever before. Things, such as cell mitochondria and cell nucleuses, can now be seen and studied in order to better help those who suffer from certain dysplasia. Looking at things under a microscope has never been more fun and more exciting.
