Electron microscopy, abbreviated as electron microscopy, has become an indispensable tool in modern science and technology after more than 50 years of development. The electron microscope consists of three parts: a tube, a vacuum device and a power supply cabinet.
The application of electron microscopy technology is based on the light microscope, the resolution of the light microscope is 0.2μm, the resolution of the transmission electron microscope is 0.2nm, that is to say, the transmission electron microscope magnifies 1000 times on the basis of the light microscope.
