Abstract
The disclosure relates to a method for producing an optical element (202), wherein a blank of transparent material is heated and/or provided and, after heating and/or after being provided is press molded, for example on both sides, between a first mold (UF) and at least one second mold (OF), to form the optical element (202) and is then sprayed with a surface treatment agent.
Claims21
1-24. (canceled)
A method for producing a headlight lens, the method comprising:
- providing a first mold;
- providing at least one second mold;
- providing a surface-treatment agent which comprises a solvent and a solid dissolved in the solvent;
- providing a gas;
- heating a blank made of soda-lime glass;
- press-molding the heated blank to form the headlight lens having at least one first optically effective surface using the first mold and the at least one second mold;
- generating a spray by thoroughly mixing the surface-treatment agent with the gas;
- exposing the at least one first optically effective surface to the spray which promotes crosslinking of oxygen ions with silicon ions on the at least one first optically effective surface;
- and
- cooling the headlight lens with addition of heat.
