Abstract

Improvements in instrumentation through the use of monochromators and field emission electron sources suggest that the ways in which the limited coherence effects are calculated must be re-examined. In this paper the effects of these approximations on the accuracy of the resultant image intensity are investigated as a function of both defocus and beam divergence.
