If more than one color is used the limit is 225 rays in each color. The wavelength for each color may be changed. The intensity of each point may be set. There may be up to six light sources with a total of six different colors. All ray tracing calculations are done using double precision floating point arithmetic.
All dimensions are in metric units.
One algorithm is a variation of the dampened least squares approach and the other is the simulated annealing algorithm. The merit function may include spot size, wavefront error, Strehl ratio, MTF, curvature, distortion, secondary spectrum, and glass thickness. Any number of parameters may be varied at once. Limits on the values of the parameters may be set manually or automatically. Optimize with up to 6 wavelengths over any field of view.
