Summary

Description
English: This is a simple sketch of the beam path of the electrons in a TEM after the illumination system. A Parallel beam of electrons enters the speciemen and are scattered in varius directions. The objective lens is used to collect all scattered beams originating from the same point on the sample in one point in the image plane (bottom). Note also that in the back focal plane (marked 'diffraction pattern') electrons originating at different point on the sample, but scattered in the same direction, are collected. Observing the electrons in this plane gives the diffraction pattern, containing information on the angular scattering distribution of the electrons. The diffraction pattern and the image are related through a Fourier transform.

This physics image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “Simple-TEM-beam-path.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
