微型彩色显示管校正透镜的设计与加工技术

Design and Manufacture of Correction Lens for Small Color Display Tubes

曝光透镜是彩管曝光台中的一个光学零件 ,它主要用于彩色CRT荧光屏制造过程中模拟电子束进行光学曝光涂屏。就是要使电子束都能一一对应地落在由光线曝光所制出的荧光粉点上 。

Exposure Lens is an optical component of color tube exposure equipment.It is mainly used for optical exposure of the chemical coating on the color CRT screen by simulating electron beam in the process of color CDT luminescent screen manufacturing. This can make the electron beam shoot to the corresponding phosphor spot made by the optical exposure,to get full screen desirable color purity.
