一、前言军用光学仪器,在很大程度上要考虑夜间能使用,因此,仪器中的分划板填料必须采用氧化锌。氧化锌填色的分划板,白天夜间都能使用。其工艺多数是采用刻划腐蚀法。但有些特殊分划板,用刻划腐蚀法,一次达不到设计要求。在同一块分划板上,它的线条粗细不等,如图1,其中部分刻线为0.008mm,部分刻线、 First, the foreword Military optical instruments, to a large extent, to consider the night can use, therefore, the instruments of reticle filler must use zinc oxide. Zinc oxide color grading reticle, can be used during the day and night. Most of its technology is the use of scoring corrosion. However, some special reticle, with the etching method, a design requirements can not be reached. In the same reticle, the thickness of its lines vary, as shown in Figure 1, in which part of the score is 0.008mm, part of the score,
