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.

Other types of the electron microscope are the scanning tunneling microscope and the scanning microscope. Both types of microscopes allow for a more in depth look than most other type of microscopes. The scanning microscope can actually allow scientists to view items in 3-D because of the excited atoms that are on a specimen. The tunneling microscope actually creates a tunneling current between the electrons on a specimen and the microscopes tip to make the image. These are both very high tech microscopes that can be used to see farther into a specimen than previously thought possible.

Various types of the electron microscope are available for people to view specimens. These types of microscopes are great to view items, such as cells that people once thought would never be seen by humans. Thanks to great technology, these specimens can be viewed in three dimensions, which can offer people more wiggle room in order to study and learn the in’s and outs of these specimens. Making strides in helping people has never been more simple thanks to the invention of the many types of electron microscopes that are on the market today.
