The scanning electron microscope has a wide range of uses in physical evidence inspection. It is very useful for the inspection of tool marks, bullets, and marks on the shell, and it is also extremely useful for hair, shooting residues and other fine physical evidence. The magnification provides magnified images of the morphological and surface structural characteristics of the physical evidence, and because of the good depth of field, it also provides clear three-dimensional images. These advantages are beyond those of ordinary optical microscopes. In addition, scanning electron microscopes and X-ray analyzers Networking also enables a qualitative analysis of test materials. This passage mainly supports such an argument, that is?
