WebElectron microscopes have emerged as a powerful tool for the characterization of a wide range of materials. Their versatility and extremely high spatial resolution render them a very valuable tool for many applications. The two main types of electron microscopes are the transmission electron microscope (TEM) and the scanning electron microscope ... WebJan 1, 2024 · Definition. A scanning electron microscope (SEM) is an instrument for imaging topography and for obtaining material information of conductive specimen using a focused beam of high-energy electrons. The electron beam is deflected in a magnetic field and performs a scanning movement in a raster pattern to capture the specimens’ surface.
