Description
We show how it is possible to produce an afocal electrostatic lens with true zoom control. This is done by relaxing the requirement that V31 equals √V51 of the original Heddle lens [D.W.O. Heddle, J. Phys. E4 (1971) 981]. A substantial range of magnification is available over a wide range of overall voltage ratios. (orig.)
