A highly efficient numerical algorithm by using multi - grid method ( mgm ) is introduced to solve the three dimensional field distribution in the present paper. formulae of the restriction and prolongation in mgm computation is deduced, and a 3d program of mgm is accomplished, which can solve the field distributions in electron optical systems for various electrostatic lenses. the 3d field distribution in an electrostatic concentric spherical model is tested with mgm algorithm and an algorithm based on finite difference method ( fdm ) respectively. comparing these two results in view of computational efficiency and computational accuracy, it appears that mgm is superior to fdm in solving electrostatic field distribution for the electron optics problem. this paper shows that the 3d field computation using mgm greatly improves the computational efficiency of field distributions in electron optical systems and shortens the computational time
