GENERAL HISTOLOGY

Detailed explanation-1: -The electron microscopes are used to achieve up to 100, 000x magnification and more than 1000 x resolution than the light microscope. At these limits, sub-cellular structures can be easily observed. Structure of the SEM: 1-Lens : here are not the optical materials (like glass), but electrical field.

Detailed explanation-2: -Transmission electron microscopes (TEM) are microscopes that use a particle beam of electrons to visualize specimens and generate a highly-magnified image. TEMs can magnify objects up to 2 million times.

Detailed explanation-3: -With electron microscopy (EM), it is possible to magnify a structure 100, 000 times. Two kinds of electron microscopic technologies have been developed: transmission electron microscopy (TEM) and scanning electron microscopy (SEM).

Detailed explanation-4: -Optical microscopy is used for the inspection at magnifications of up to 1, 000 times microstructures. Electron microscopy with magnifications of up to 500, 000 times is typically used for failure analysis in R&D labs and in educational institutions.

Detailed explanation-5: -transmission electron and scanning electron microscope. An electron microscope that provides high magnification (10, 000 to 100, 000x) of ultra-thin sections of the specimen.
