The present work is concerned with computer design within the field the optics of charged particles. This investigation is involved designing an electrostatic Einzel lens using Schinke's model under certain magnification conditions (zero magnification). An analytical function named by Schiske's model has been used to represent the potential field distribution for the electrostatic lens (Einzel lens). By solving the paraxial ray equation using the 4th order Runge-Kutta method the charged particle beam trajectory and its derivatives traversing the lens has been found. The einzel lens axial potential distributions and its 1st and 2nd derivatives and the beam trajectory and it's 1st and 2nd derivatives are calculated from solving the paraxial ray equation and all used to determine the optical properties of the proposed electrostatic lens like magnification, focal properties and aberrations (spherical and chromatic).
