Scanning Electron Microscopy (SEM) Basic Working Principle

• Electron gun emits a steady electron beam;
• Electron beam through an electromagnetic lens system forms a fine beam spot on the sample surface;
• Incident electron interacts with the sample, can stimulate secondary electrons, backscattered electrons, X-rays and other signals;
• Scanning electron beam under the control of the magnetic field ,on the surface of the sample point by point progressive scanning;
• Use of the detector receiving the signal, amplifies, Sample surface image can be formed after collection., thus reflecting the sample surface topography, composition and other information.
