关于透镜偏心差的问题,目前国内看法不一,生产中出现的矛盾较多。不久前制定的“几何光学常用术语、符号”国家标准(草案)中,对透镜的偏心差下了一个含糊的定义,即“透镜外圆中心轴和光轴的偏离程度”。把此问题暂做“悬案”。因此,无论从理论上,还是从实践上都有必要进一步研究透镜偏心差的问题。现将德国的关于偏心差的新标准刊登出来,作为参考,以期引起大家的讨论。
With regard to the problem of lens eccentricity, the current domestic opinions are different, and there are more contradictions in production. Not long ago developed “geometric optics commonly used terminology, symbols,” the national standard (draft), the lens eccentricity under the ambiguity of a definition of “the lens outer central axis and optical axis deviation.” This issue temporarily “pending case.” Therefore, both in theory and in practice, it is necessary to further study the problem of lens eccentricity. The German new standard on eccentricity is now published as a reference, with a view to arouse the discussion of everyone.
