Abstract
A two-element gradient-index photographic objective was designed. It operates at f/2 and has a focal length of 50 mm. The half-field of view is 21.8 degrees . The design is compared to the six-element new double Gauss photographic objective and performs well in comparison.Year: 1982 PMID： 20389791 DOI： 10.1364/AO.21.000993
