Abstract A reflective optics system is described that will uniformly heat or transfer momentum to a spherical target. Six laser beams or three split beams are incident along three mutually perpendicular axes. The beams are reflected from cones with a 45/sup 0/ half-angle onto an aspheric reflector wing shaped to impart uniform heat or momentum to the target. A sample calculation shows that, for a target sphere with 1.5 index of refraction, 93% of the energy incident on the target is transmitted into the target. For smaller indices, a greater fraction of the incident energy is imparted to the target. The design provides completely uniform transmitted light as well as nearly orthogonal distribution of light over the target and is relatively insensitive to alignment errors.
