Improved hybrid SMS-DSF method of nonimaging optical design

The hybrid SMS-DSF method of nonimaging optical design combines the discrete simultaneous multiple surface (SMS) method with the dual-surface functional (DSF) method to obtain improved optical performance relative to the discrete SMS method alone. In this contribution we present a new extension of the hybrid SMS-DSF method that uses differential ray tracing to produce designs having significantly improved performance relative to the original hybrid SMS-DSF method.
