Question

advantages and disadvantages of electron microscope....


guys plz answer... in brief..

Answer 1

The electron microscope is a type of microscope that uses a beam of electronsto 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.The primary advantage is its powerful magnification.

The potential runs the gamut of scientific fields including biology, gemology, medical and forensic sciences, metallurgy and nanotechnologies.

EMs also have many technological and industrial applications, such as semiconductor inspection, computer chip manufacturing, quality control and can even be used as part of a production line.

The main disadvantages are cost, size, maintenance, researcher training and image artifacts resulting from specimen preparation.

This type of microscope is a large, cumbersome, expensive piece of equipment, extremely sensitive to vibration and external magnetic fields.

It needs to be kept in an area large enough to contain the microscope as well as protect and avoid any unintended influence on the electrons.

Upkeep involves maintaining stable voltage supplies, currents to electromagnetic coils/lens and circulation of cool water so the samples are not damaged or destroyed from heat given off during the process of energizing the electrons.

Special training is required to learn the involved processes of specimen preparation, to minimize and recognize preparation-related artifacts and to operate the microscope itself.

Despite these disadvantages, EMs are assets to high-end research laboratories; this powerful piece of equipment has resulted in innumerable advances in science and industry.
