Abstract

An electron gun for a cathode ray tube has a main lens section and a dynamic astigmatism and focusing (DAF) lens section. According to the invention the DAF lens section is arranged on the main lens section for forming an integrated DAF main lens section. The total length of an electron gun comprising an integrated DAF main lens section is considerably smaller than that of the known electron gun. The invention further relates to a cathode ray tube comprising an electron gun.
