Abstract

We have developed a new method other than traditional technique based on ray tracing and optimization algorithm to design arbitrary aspherics. Analytic definition of the aspheric surfaces is done away with and numerical solution of nonlinear difference equations called Aspheric Intrinsic Equations (AIE) is implemented instead. Simulation results compared with traditional optical design software are presented, which prove that this new method is more effective and reliable in designing aspheric surfaces.
