Abstract
Accurate calculations of focal properties of the two-tube electrostatic lens are extended to cover a range of voltage ratios from 1.1 to 10000. The accuracy of the calculations is discussed in detail. For voltage ratios near 6400 the lens is found to be telescopic. Results are given in tabular form and as P-Q (object-image) curves. A simple analytical form for the focal properties of lenses with near-unity voltage ratios is given.Citation
