text: The condenser lenses are responsible for primary beam formation, while the objective lenses focus the beam that comes through the sample itself (in STEM scanning mode, there are also objective lenses above the sample to make the incident electron beam convergent).
text: Then the EM’s lenses re-focus the beam into a Fourier-transformed image of the diffraction pattern for the selected area of investigation.
