Jonah Odom · Answer 1

A scanning electron microscope is a type of specialized electron microscope, which is used to study the surface of a smaller, solid sample, such as fossils, sediments, in a raster type of pattern, with a beam of electrons. This electron beam is comparatively low energy. The source of electrons and the type of electromagnetic lenses used in this microscope are similar to the one that is used in the transmission electron microscope.

It is very widely used and has various advantages. It provides the topography of the solid surface of the sample, the morphology of the sample and composition of the taken sample. These are key information used in a variety of both industrial applications as well as in the science laboratories.
