Some Information about Electronic Microscope

The electronic microscope is a type of microscope that creates an image of the specimen by using a beam of electrons. It has an ability of much higher magnifications and a greater resolving power compared to a light microscope. These two features allow it to see much smaller objects in finer detail. They are large, expensive pieces of equipment so that they require the trained personnel to operate them.

It is known that all the electron microscopes can control the path of electrons by using the microscope lens. The electrons are very sensitive to magnetic fields so that it can be controlled by changing the current through the lenses.

The resolving power of a microscope is directly associated with the wavelength of the irradiation that can be used to form an image. Reducing wavelength increases resolution so that it can increase the resolution of the microscope if it increase the accelerating voltage of the electron beam. It is proven that the modern electron microscopes can be designed to magnify objects up to about two million times. It has been used to examine biological materials (such as microorganisms and cells), metals and crystalline structures, a variety of large molecules, medical biopsy samples and the characteristics of various surfaces.
