Investigation of symmetrical two-cylinder lens.
Ali A. Al-Azawy
Abstract
In the current work, The immersion lens was investigated as a two-cylinder symmetrical lens with different radii, and
this lens is studied in the accelerated mode and in the deceleration mode. Their main points have been studied in
these cases. Where firstly the lens has a negligible gap width and secondly with a dysfunctional gap width, and all
the cardinal points can be obtained as a function of the voltage ratioIn the current work, The immersion lens was investigated as a two-cylinder symmetrical lens with different radii, and
