'''Electron microscope''' is a type of [[microscope]] that uses a beam of [[electron]]s to create an image of the specimen. It is capable of much higher magnifications and has a greater resolving power than a light microscope, allowing it to see much smaller objects in finer detail. They are large, expensive pieces of equipment, generally found in professional laboratories.

== History ==

The electron microscope was first developed in the 1930s by the German physicists [[Ernst Ruska]] and [[Max Knoll]]. Ruska, in particular, is often credited with the invention of the electron microscope. He was awarded the [[Nobel Prize in Physics]] in 1986 for his work.

== Types of Electron Microscopes ==

There are two main types of electron microscopes:

* '''Transmission Electron Microscope (TEM)''': This type of microscope transmits a beam of electrons through a very thinly sliced piece of specimen. The electrons interact with the atoms in the specimen which changes the beam's direction and speed. These changes are detected and turned into an image.

* '''Scanning Electron Microscope (SEM)''': This type of microscope scans a beam of electrons across the surface of a specimen. Secondary electrons are emitted from the specimen's surface as a result of the electron beam. These secondary electrons are detected and turned into an image.

== Applications ==

Electron microscopes are used in a variety of scientific fields. They are used in [[biology]] to study cells and tissues, in [[material science]] to study materials at the nanoscale, and in [[geology]] and [[metallurgy]] to study the properties of minerals and metals.
