Shadow

SHADOW is a ray-tracing program developed by F. Cerrina et al. at the University of Wisconsin. It's optimized for designing synchrotron radiation beamline optics. Shadow is singular in that it generates and traces a beam long the optical system, a collection of elements placed in sequential order. The Shadow code tracks the source sequentially through each element in the sequence and calculates the direction of the output and the decrease in intensity of the beam. This information and more can be found here.
