This article provides general information about electron microscopy analysis. The general structure, types, optical scheme and working principle of electron microscopes are introduced. Information about "Levenhook" microscopes is provided. Sample preparation technology, replicates and thin samples were analyzed. The proCesses of determining the structure of disloCations with the help of replicas of the electron microscope are explained. Characteristics of raster electron microscope, emission electron microscopes were analyzed.

Electron gun insulator, vrasmthermal cathode, electrode, anode, condenser lens, diaphragm, two-level deflection system, lens, diaphragm optics, reception, detector of secondary electrons, crystal leaf spectrometer, proportional counter, preamplifier, gain block, electric ray tubes.
