The flight trajectories of two electrons with initial KE of 5 eV and two electrons with initial KE of 95 eV from two different axial positions. In the left enlarged view, e3 and e4 are the two different axial positions. In the right enlarged view, M is the focused spot of the two electrons with 95 eV, and N is the focused spot of that with 5 eV.
