Ronchigram Depending on Accelerating Voltage of Electron Beam
- Practical Electron Microscopy and Database -
- An Online Book -  

This book (Practical Electron Microscopy and Database) is a reference for TEM and SEM students, operators, engineers, technicians, managers, and researchers.


The Ronchigrams in STEMs operated at lower accelerating voltages have smaller semi-angles than those operated at higher accelerating voltages. These smaller semi-angles represent smaller flat-contrast areas where the probe coherently converges on specimens in STEMs.
