    Patent number: 4489107
    Abstract: Process for producing an optical component, particularly a metal reflector. A glass prism is sprayed with several coatings of a metal alloy. The spray jet is guided in such a way that uniform coating thicknesses are obtained. The resulting sprayed part is removed from the glass prism and the surface formed against the prism is used as a metal reflector. Additional coatings can also be applied after removal to improve reflectance characteristics.
