Scanning electron microscope is imaging technique of revealing the surface topography of a Specimen when a electron beam with a high energy emitted from an electron gun is incident upon the surface by frame frequency scanning. Secondary electrons and back scattered electrons containing all kinds of physical information are excited from the surface. The intensities of secondary electrons and back scattered electrons depend on the surface morphology, element and crystal orientation. When the signals of secondary electrons and back scattered electrons are amplified, the terminal of a computer will display an image of the reflecting surface characteristics of the specimen. Model JSM-IT300 scanning electron microscope is mostly applied in observing the surface topography and it has been an important implement in materials science, biological science and all industrial departments. JSM-IT300 scanning electron microscope can be used for nonconductive samples directly, and mining industry. Biological samples, such as tissue fat,flower powder and rhizome, etc., can be observed directly after special and simple preparation.
