After more than 50 years of development, electron microscope has become an indispensable tool in modern science and technology. An electron microscope consists of a lens barrel, a vacuum device and a power cabinet.
The application of electron microscope technology is based on optical microscope. The resolution of the optical microscope is 0.2μm, and that of the transmission electron microscope is 0.2nm, which means that the transmission electron microscope is enlarged by 1000 times on the basis of the optical microscope.
