| Abstract: | The 7th order geometrical aberration of rotationally symmetrical electron optic system and their expressions are given by using the eikonal method when the electric and magnetic fields exit.The 7th order geometrical aberrations can be divided into 8 types according to the power of initial or boundary conditions.There are 35 geometrical aberration coefficients. |
