摘要
The invention relates to a method for producing a freeform fresnel surface having a number of fresnel facets (12) with a respective fresnel segment surface (10) and a trailing edge (28). In the method, the production of the freeform fresnel surface occurs by means of machining processing of a starting body based on the construction data for the freeform fresnel surface. With the aid of the circular cylinder casing surfaces and/or cone casing surfaces, the projection of the edges of the fresnel facets on the x-y-plane represent circular paths for the creation of the construction data.
