    • The present invention relates to beam shaping elements, such as for example lenses, diffractive elements or mirrors, which exist as composites, comprising an inorganic substrate and an organic substrate in the form of a polymer, which can be thermally cured at temperatures between 0 and 180° C. Preferably, the organic polymer is selected from the group consisting of polyurethanes and silicones. According to a preferred embodiment, it is a polyurethane. The beam shaping elements according to the present invention have advantageous properties with respect to precision, rigidity and durability and can further be produced in an easy way by means of an economic method, which method is also subject of the invention.
