Transmission Electron Microscope (TEM) Transmission electron microscopy uses an electron beam that penetrates a sample to image, which requires the sample being observed to be "transparent" to the incident electron beam. Transmission electron microscopy is widely used in materials science and biology. Since electrons are easily scattered or absorbed by objects, the penetration is low, and the dens...

The major limitations on TEM performance are spherical aberration (also known as aberration), chromatic aberration, and astigmatism. The spherical aberration and chromatic aberration limit the resolution of traditional TEM. Both of these defects are inevitable when using static rotational symmetric electromagnetic fields. Ball aberration is the most important factor determining the performance of ...
