WebIn the diffraction mode, β is determined by the camera length. If there is no lenses after the TEM specimen, β would be simply be β = r/ (L+a 2 ). As shown in Figure 4938b, in STEM and TEM diffraction modes, the diffraction pattern is similar to convergent beam electron diffraction (CBED) in TEM mode because of using the focused electron beam.
