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

 

=================================================================================

The deflection angle in electron holography is controlled by the applied voltage to the filament electrode, and the applied voltage is limited by the electric discharge, e.g. ≤ 300 V for some systems. In the case of off-axis electron holography in TEMs as shown in Figure 4204, the deflection angle is the angle α.
