摘要

本文给出了彩色显象管对称校正透镜的计算机辅助设计

指出若适当调节曝光光源的位置

对着屏误差的分布和透镜镜面的形状均会产生有益的影响。

Abstract

This paper gives the computer adied design of aspherical

rotarysymmtrical correcting lens for the color picture tube. It shows that properly adjusting the position of the exposing source would have useful influence on the distribution of landing error and the profile of lens surface.
