WebThe introduction of the first commercial scanning electron microscopes (SEMs) in 1965 opened up a new world of analysis for materials scientists. Ultrahigh voltage TEM instruments (up to 3 MeV at CEMES-LOE/CNRS in Toulouse, France, and at Hitachi in Tokyo, Japan), in the 1960s and 1970s gave electrons higher energy to penetrate more deeply … WebAs in optical microscopes, the resolution of an image formed by a scanning electron microscope is limited by aberrations. Achieving the diffraction-limited sub-nanometer resolution is difficult in practice. Certain shortcomings of the lenses can be corrected, and others can be at least minimized. A summary of the three most important defects ...
