Abstract: An analysis is made of the conditions of focusing of non-Gaussian beams by an ideal thin lens which transfers light from a laser projection tube (quantoscope) to a large screen. It is shown that, under certain conditions, the resolving power of an image on a distant screen can be several times higher than the electron-optical resolving power of such tubes.
