Ray tracing for aspheric lenses
WebJun 25, 2015 · An aspheric lens design method was presented for an application to LED collimating illumination. The method was derived from a basic geometric-optics analysis and the powerful optimization capability of particle swarm method. By using this method, a highly collimating aspheric lens based on a point source was designed. To verify the … WebA leading lens design tool that combines advanced ray tracing, analysis, and optimization methods with an easy-to-use, ... reflective, diffractive, gradient index, aspheric, and freeform optics.
