Abstract
An optical system has a plurality of surfaces. In addition, a specification of a sequential ray trace through the optical system specifies an order of surface elements for tracing rays through the optical system. The sequential ray trace may be for stray light rays rather than for the primary rays propagating through the optical system. The surface elements include a surface set. The surface set includes at least two of the surfaces in the optical system. Rays are traced through the optical system according to the sequential ray trace. For example, the specification of the sequential ray trace may also specify a maximum number N of surface-intersections for the surface set. Rays are traced through the optical system with up to N surface-intersections with the surfaces in the surface set, and without regard to the order in which rays intersect the surfaces in the surface set.
