摘要
介绍一种超大孔径摄像镜头 ,其结构型式为复杂化双高斯型 ,主要光学参数为f′ =6 0mm ,F =0 .7,β =-1/13× ,L =-6 5 0mm ,系统达到MTF =0 .5的成像质量所对应的空间频率大于 2 0lp/mm。对该镜头的结构特点进行分析讲讨论 ,并给出了各种像差曲线 ,传函曲线和渐晕图。
A high speed camera lens featured with a relative aperture f/0.7 was designed. The optical configuration of complicated double Gauss objective was adopted to yield f′ =60mm, F =0.7, β =-1/13, L =-650mm and MTF =0.5 at a spatial frequency of 20lp/mm. The construction features of the lens are discussed. The aberration curves, transform function and vignetting of the wide aperture lens are presented.
