Abstract
Electron optics model of a cathode lens consisting of hyperboloid of rotation and a plane called "a needle above plane" is presented. The most important result is asymptotic crossover radius changing in wide range of tip radius changing and the half angle of the apex. The results can be useful for the description of thermionic guns for nanolithography.
