Paper Abstract

Continuous development of lenses for photographic applications has led to the design of a variety of high performance objective lenses. Several fixed focal length lens designs are concentrated upon in the paper with particular attention being paid to the utilization of special glass types and how they influence the overall performance of the final lens design. The paper also illustrates how severe requirements imposed at the design stage have resulted in substantial improvements in overall performance compared to previous lens designs. Important features including low f/number, low T/number, low residual secondary colour and constant colour balance are described for different focal length lenses.
