According to the Encyclopdia Britannica, there are many kinds of electron microscopes:
"The transmission electron microscope (TEM) can image specimens up to 1 micrometre in thickness. High-voltage electron microscopes are similar to TEMs but work at much higher voltages. The scanning electron microscope (SEM), in which a beam of electrons is scanned over the surface of a solid object, is used to build up an image of the details of the surface structure. The environmental scanning electron microscope (ESEM) can generate a scanned image of a specimen in an atmosphere, unlike the SEM, and is amenable to the study of moist specimens, including some living organisms.
Combinations of techniques have given rise to the scanning transmission electron microscope (STEM), which combines the methods of TEM and SEM, and the electron-probe microanalyzer, or microprobe analyzer, which allows a chemical analysis of the composition of materials to be made using the incident electron beam to excite the emission of characteristic X-rays by the chemical elements in the specimen."

the electron microscope is called that because it uses beams of electrons to accurately measure distances on atomic scales
scanning electron microscope
An electron microscope is named as such because it uses a beam of accelerated electrons to generate high-resolution images of objects at a much higher magnification than light microscopes. This electron beam is used to visualize the object being studied, allowing for extremely detailed and magnified views.
A Dutch father and son named Zach and Hans Janssen created the first light microscope in 1590. The electron microscope was invented in the 1930's. The scanning electron microscope was invented in the 1980's.
There is a compound light microscope, an scannignn electron microscope, and transmission electron microscope.
what is the principal of electron microscope
Stereomicroscope, Compound Microscope, Phase-contrast microscope, electron microscope, Scanning-electron microscope, Transmission electron microscope, Confocal-scanning microscope. THESE ARE JUST SOME. :)
The four main types of microscopes are the Light Microscope, Electron Microscope, the Transition electron microscope and Scanning electron microscope.
An Electron Microscope is used to study the contents of a nucleus.
The Compund light microscope allows people to view living cells. With the electron light microscope peole can only view dead cells but with very high detail. The electron microscope is also much more expensive than a compound ligh microscope. The compound light microscope is also much easier to transport from place to place, as the electron microscope is not.

The first electron microscope was developed by a German physicist named Ernst Ruska in 1931, along with his colleague Max Knoll. They were awarded the Nobel Prize in Physics in 1986 for their invention.
