Lens design for a 609.6-mm, f/6, 30 degrees -field objective.
As a test problem, an attempt was made to optimize a Heliar aerial photography lens already designed for optimum performance by classical methods. Improved performance was obtained in off-axis image resolution and contrast. Evaluations of both lens designs are given, together with the modifications prescribed as a result of machine analysis with the LASL program, which analyzes statistically the traced skew rays generating the geometrical image spots.
