Electron Microscope (EM): Principles and Types

(2) Scanning Electron Microscope (SEM): It is the second type of EM, first built by Knoll (1935) but it was commercially developed by Cambridge Instruments (1965). It is used to study the three dimensional images of the surfaces of cells, tissues or particles. The SEM allows viewing the surfaces of specimens without sectioning.
