Abstract
Many optical devices have certain light diagrams, which correspond to the world standard. However, to achieve this, one can use a lens including the freeforms, which provide necessary geometry for the light distribution. Freeform surfaces have additional capabilities that may provide a better solution to the asymmetry problem with higher efficiency or fewer elements. This method implies that we know the type of source and the light distribution. In the paper various types of freeforms are considered. Results of freeform modeling forming required light distribution for a given optical source are presented. Effective methods of freeform modeling using Zemax (OpticStudio) are discussed.
