Abstract

Ray mapping method can greatly simplify the freeform illumination lens design. However, the result obtained by the ray mapping method sometimes deviates much from the design target. Therefore, we present a construction of double freeform surfaces based on nonlinear least squares and non-uniform rational B-spline surfaces (NURBS) to minimize the deviations. By this way, we can get a smooth double-freeform-surface lens with good optical performance.
