Analysis and correction of secondary color in optical systems.


A technique of chromatic image analysis for optical systems has been developed. The advantages of the technique in giving the lens designer an understanding of the significant inherent sources of secondary color in a particular design are demonstrated. Methods of reducing the secondary color through optimization of glass choice and the actual lens configuration are shown in the application of the analysis to the design of a highly corrected, finite conjugate relay lens.
