| Abstract: | 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. |
