Low-energy electron microscope

Low-energy electron microscopy uses an electron beam of 0.1-10 keV to irradiate the sample and images by detecting backscattered electrons and secondary electrons. It can observe the surface morphology of non-conductive materials and is used for analyzing coating thickness, detecting paper fiber structures, and observing surface defects in plastics.
Selection
When selecting, consider the sample's conductivity to determine whether coating is needed, match the electron gun type based on resolution requirements, ensure the sample chamber size accommodates the object to be tested, confirm the electron energy range according to testing standards, and refer to maintenance costs to choose the vacuum system configuration.
