Scanning Electron Microscope (SEM) Experiment Service

Instruction manual

First Edition (Revised on April, 2016)


The characteristics for Scanning Electron Microscope (SEM) is simple sample preparation, wide adjustable range of magnification, image resolution, depth of field, and etc. In recent years,SEM has been widely used in biology, medicine, and other field. The electron beam of the SEM does not pass through the sample, only the surface of the sample is scanned to excite the secondary electrons. The image is a three-dimensional image, reflecting the surface structure of the specimen. So SEM specimens do not need to make thin slices.

The basic function of SEM is to observe the surface morphology of various solid samples. The depth of field is the features fo SEM, the observation can be the surface of sample, a cut surface, or a section.
