Scattering and Phase Contrast for Amorphous Specimens

  • Ludwig Reimer
Part of the Springer Series in Optical Sciences book series (SSOS, volume 36)

Abstract

Elastic scattering through angles larger than the objective aperture causes absorption of the electrons at the objective diaphragm and a decrease of transmitted intensity. This scattering contrast can be explained by particle optics. The exponential decrease of transmission with increasing specimen thickness can be used for quantitative determination of mass-thickness or of the total mass of an amorphous particle, for example.
