The single-channel detection systems are the most often used for the detection of the Secondary
Electrons (SE) and Backscattered Electrons (BSE) in the Scanning Electron Microscope (SEM). Sometimes the segmented detector of BSE according to the azimuthal angle is used to optimize the material (sum signal) and topographic contrast (subtracted signal). To achieve high lateral resolution the
specimen is usually immersed in the strong magnetic field and/or in the strong electrostatic field, in the
case of the operation at low primary beam energies; we call this regime Cathode Lens Mode (CLM).
Those fields strongly influence the trajectories of the signal electrons.
