摘要
偏心差是红外透镜设计、制造的重要参数,直接测量难度大、成本高。从 GB/T 7242中相关定义出发,推导了透镜偏心差与两个球面的球心差之间的关系,并与 Zemax仿真结果和已有关系式的计算结果进行了对比,验证了其在用可见光下反射成像方式中心偏差测量仪测量计算红外透镜偏心差的有效性。
Abstract
Prejudicial aberration is an important parameter in design and manufacture of infrared lenses, direct measurement of which is hard and costs high. From the definitions in GB/T 7242, the relationship between prejudicial aberration and spherical center aberrations of a lens is deduced. Compared with the simulation result by Zemax and calculation result of an existed formula, the validity of the relationship is verified.
