CRT screen exposure device utilizing improved light means |
摘要 |
An improvement is provided in a cathode ray tube screen exposure device wherein both the intensity and the shaping of the exposure radiation is improved by employing two conjunctive sources of radiant energy. The alpha source is positioned in a substantially superjacent manner relative to a related beta source on a substantially common optical axis. Each source is separately adjustable in a limited arcual manner, during operation of the device, to achieve optimized light output in the form of a conjunctive source of radiant energy of optimized shaping.
