Estimating the term…
The invention relates to a method for producing an element comprising a substrate and at least one anti-reflection coating with pores. The dimensions of the anti-reflection coating are below the wavelength of visible light or the neighbouring spectral ranges. The invention also relates to an element produced according to this method with at least one anti-reflection coating, for example optical lenses, mirrors or other optical components. The optical anti-reflection coating of these elements is essentially improved.
Process for producing an element comprising a substrate and at least one antireflection coating having pores, the dimensions of the antireflection coating being below the wavelength of visible light or neighboring spectral regions, comprising the steps
Process according to one or more of the preceding claims, in which a single or multiple coating is first produced, one or more phases are subsequently dissolved out by suitable solvents and then exposed to an etching solution for so long a time that pores having a suitable depth are produced on the substrate at the sites not covered by the polymer(s).
Process according to one or more of the preceding claims, in which a single or multiple coating is first produced, one or more phases are subsequently dissolved out by suitable solvents, then exposed to a suitable solution of precursor molecules, and a sol-gel procedure is subsequently carried out with the precursor molecules being separated out.
Process according to one or more of the preceding claims, in which a single or multiple coating is first produced, suitable precursor molecules having already been added to one or more solutions, a sol-gel procedure is then carried out with the precursor molecules being separated out, and one or more of the polymer phases are subsequently removed.
Process according to one or more of the preceding claims, in which a single or multiple coating is first produced, one or more phases are subsequently dissolved out by suitable solvents and the coating thus obtained is then vapor-plated with a material in such a manner that the pores present in the coating are filled.
