作者曾于一九七四年第九期《ОМП》刊载的“中心偏定义和测量方法”一文中,对国标规定的中心偏公差的标注符号,做过探讨并认为用现有的任何一种检测方法都不能直接测出中心偏公差的量值。本文拟就采用中心偏公差的目的及其最合理的给定形式,进行某些探讨。为使光学机械仪器获得预定的成象质量,光学计算必须保证原始光组具有一定的裕量,以便藉此弥补由于材料的光学性能偏差以及零件制造和组装误差所引起的象质的变坏。在理想情况下,光学计算应包括原始光组的数据、在仪器制造过程中允许光组变坏的公差数据、包括光学表面中心偏在内的所有参数对于象质的综合影响的数据、单个表面的偏移量以及单个透镜及胶合透镜的偏移量和倾斜度对光组象差影响的数据。
In his article entitled “Center Definations and Measurement Methods” published in “ОМП”, Issue No. 9 of 1974, the author made a study on the symbols of center-level tolerances stipulated by the national standard and considered that any existing one Detection methods can not directly measure the amount of center deviation tolerance. This article intends to use the center of the partial tolerance purpose and the most reasonable given form, to conduct some discussion. In order to obtain a predetermined imaging quality for the optical machinery, the optical calculation must ensure that the original optical set has a margin in order to compensate for deterioration of the image quality due to variations in the optical properties of the material and errors in the manufacture and assembly of the parts. Ideally, the optical calculation should include data from the original light set, tolerance data that allows the light set to deteriorate during manufacture of the instrument, including all parameters within the center of the optical surface, data for the combined effects of the image quality, Offsets, and offsets and tilt of individual and cemented lenses on aberration of the light set.
