Method for production of transmission-enhancing and/or reflection-reducing optical coatings

摘要

The invention relates to a method for producing transmission-enhancing and/or reflection-reducing coatings against or on substrates by flame coating. It is based on the object of suggesting a production method for anti-reflective coatings that works in an environmentally friendly manner with the least possible complexity in terms of work time and energy. It is comprised in that a silicon-containing precursor is thermally or hydrolytically decomposed by a hydrocarbon and/or hydrogen flame using an oxidant and is applied to the substrate directly from the gas phase as an SiO_x(OH)_(4-2x) coating, wherein 0x(OH)_(4-2x) coating has a residual carbon content of 0 to 10%.
