الملخص الانجليزي
In the present work, the focal properties of electrostatic lens consist of three cylindrical electrodes were intensively investigated . Each electrode spaced of (0.1) diameter apart. Special case such as a zoom lens is considered and the results are obtained as a function of the final-to-initial voltage ratios. It is found that the three-element lens could be operated with the whole focus properties in a useful mode. The calculations are carried out by using the LENSYS software package.
