CORRECTING LENS FOR COLOR CATHODE RAY TUBES

摘要

A correcting lens for use in the formation of a color television picture tube screen that is excitable by an electron beam comprises a plurality of individually contoured elements that extend from a point common to all elements to an edge of the lens. Adjacent elements are separated by boundaries and all boundaries extend radially outward from the common point. Each element is individually contoured to direct light onto predetermined paths of the electron beam toward a similarly shaped corresponding area of the screen.
