Scanning Electron Microscope (SEM)

WebSEM is one of the main testing instruments for in situ analysis of microareas. It has the advantages of high resolution, large depth of field, high magnification, and strong stereoscopic vision. Photographs taken by SEM have higher magnifications and clearer definitions than those by optical microscopy. WebOct 27, 2024 · It was stated in Sect. 2.4.6 that the magnification in the SEM is changed by varying the size of the scan on the specimen. The smaller scan produces higher magnification and vice versa. As the size of the scan gets smaller at higher magnification, the size of the picture elements is proportionally reduced to accommodate picture …
