what is application of Transmission Electron Microscope?

Answer 1

The transmission electron microscope has three essential systems: (1) an electron gun, which produces the electron beam, and the condenser system, which focuses the beam onto the object, (2) the image-producing system, consisting of the objective lens, movable specimen stage, and intermediate and projector lenses, which focus the electrons passing through the specimen
The electron microscopes in the AMCL are available to researchers to provide high-resolution images and microanalysis. The conventional scanning electron microscopes (SEM) can provide imaging to magnifications of 50,000X or more, and the field emission SEM can provide images up to 500,000X. The FEGSEM is also equipped with an electron backscatter pattern system to provide crystallographic information also. The transmission electron microscope (TEM) can provide images up to 550,000x from specially prepared, ultra-thin samples, and also provide electron diffraction patterns from areas as small as 25nm.
