This is consisting of a coil wire on the outside of a tube, which is called a solenoid.

It also requires to use a thermionic gun to serve as an electron source.Įlectromagnetic and electrostatic lenses are used by electron microscopes. More so, you need to use coiled electromagnets in place of glass lenses. Moreover, instead of using an eyepiece to view the specimens, it requires the user to utilize the electron micrograph to view the sample on a screen. But, instead of using particles of light or photons, concentrated electrons or charged particles from the outside portion of atoms are utilized to view a tiny object. This type of microscope should allow researchers to take a look at specimens at a size measureable only by nanometer standards.īasically, the use of electron microscopes offer the same principles to that of optical microscopes. One of the most impressive innovations in terms of microscope technology is the invention of the electron microscope.
