The scanning electron microscope (SEM) has become one of the most widely utilized instruments for materials characterization. Given the overwhelming importance and widespread use of the scanning electron microscope (SEM), it use universities and colleges with materials-oriented programs to provide instruction in the basic operation.
the image resolution of the scanning electron microscope (SEM) is about an order of magnitude poor and sharp. It is able to image bulk samples up to many centimetres in size and (depending on instrument design and settings) has a great depth of field, and so can produce images that are good representations of the three-dimensional shape
