摘要
本文阐述了光栅光密度的测试情况,文中叙述了多种不同栅距,制造工艺各异的光栅母板、复制品等的光密度测试数据,分据了光栅其他参数对光密度的影响,并对光栅密度标准的制定提出了一些想法。
The measurement of optical density of gratings is described in this paper. Measuring data of various gratings——ruling ones or replicated ones, with diferent pitchs and different making methods——and presented. Some grating parameters are discussed which affect the optical density. A suggestion on the draft of technical standard of grating optical density is presented.
