Electron microscope, referred to as electron microscope, the English name ElectronMicroscope (referred to as EM), after more than 50 years of development has become the modern science and technology in the indispensable and important tools. Electron microscope consists of three parts: mirror tube, vacuum device and power supply cabinet.
The application of electron microscope technology is built on the basis of optical microscope, the resolution of optical microscope is 0.2μm, the resolution of transmission electron microscope is 0.2nm, that is to say, the transmission electron microscope in the optical microscope on the basis of the magnification of 1000 times.
The electron microscope consists of three parts: the lens barrel, the vacuum unit and the power supply cabinet.
