Both light microscopes and electron microscopes use radiation (light or electron beams) to form larger and more detailed images of objects (e.g. biological specimens, materials, crystal structures, etc.) than the human eye can produce unaided. (See also: What is eyesight ?) An electron microscope is a microscope that uses beams of electrons instead of rays of visible light to form highly magnified images of tiny areas materials or biological specimens. Comparing light vs electron microscopes is made more complicated by the fact that there are different types of electron microscopes. The two main types of electron microscope are the Transmission Electron Microscope (TEM) and Scanning Electron Microscope (SEM). Other types of electron microscope include the Scanning Tunneling Microscope (STM) and Field Emission Transmission Microscope (FE-TEM). Brief notes, see the tables lower down this page for figures, explanations and comments:
See the table at the bottom of this page for the advantages and disadvantages of light vs electron microscopes. The following simple block diagram shows some of the basic similarities between light microscopes and electron microscopes (in general) by comparing the radiation pathways for a light microscope with a general electron microscope. Very simple block diagrams of Electron vs Light MicroscopesCompare Electron Microscopes vs Light Microscopes (Physical Aspects)As there are different types of electron microscopes and capabilities vary the following comparison of electron microscopes with light microscopes is very general (including 'typical' rather than exact figures).
Above: Table comparing the physics of light vs electron microscopes Compare the Advantages and Disadvantages (i.e. limitations of use) of Electron Microscopes vs Light MicroscopesDue to constraints imposed by the ways in which different types of microscopes produce images, some microscopes can be used in certain ways that others cannot. For example, it is not possible to observe individual molecules using a light microscope or to watch living processes happen using an electron microscope.

What is the main difference between a light microscope and an electron microscope?Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes.
What are the 3 main differences between light and electron microscopes?Differences between Light Microscope and Electron Microscope. What is the difference between a light microscope and an electron microscope BBC Bitesize?There are two main types of microscope: light microscopes are used to study living cells and for regular use when relatively low magnification and resolution is enough. electron microscopes provide higher magnifications and higher resolution images but cannot be used to view living cells.
What is the main difference between a light and electron microscope multiple choice question?-The light microscope uses light, and the electron microscope uses electrons. When an object is viewed through a light microscope with oculars that magnify 20x and a high-power objective lens that magnifies 100x, what is the total magnification of the object?
