The invention relates to a layer system comprising a metal substrate (1) on the face (A) of which the following layers are applied in the specified sequence from the inside to the outside: 4) a layer made of a material selected from substoichiometric oxides and oxide nitrates of titanium and zirconium or from metals selected from titanium, zirconium, molybdenum, platinum, and chromium or an alloy using one of said metals or at least two of said metals, 5a) a layer made of a nickel alloy with chromium, aluminum, vanadium, molybdenum, cobalt, iron, titanium, and/or copper as the alloy partner or a metal selected from copper, aluminum, chromium, molybdenum, tungsten, tantalum, titanium, platinum, ruthenium, rhodium, and alloys using one said metals or at least two of said metals, or iron, steel, or stainless steel with the proviso that the layer can only consists of aluminum if the reflector layer 6) is made of aluminum and that in this case, the aluminum of the layer 5a) is sputtered, 6) an optically dense reflector layer made of a highly pure metal, 7) a layer selected from substoichiometric oxides of titanium, zirconium, hafnium, vanadium, tantalum, niobium, or chromium and from metals selected from chromium, titanium, zirconium, hafnium, vanadium, niobium, tantalum, tungsten, molybdenum, rhodium, and platinum and alloys using one of said metals or at least two of said metals, 9) a layer which has a lower refractive index (LI layer) than the directly adjoining layer 10) (HI layer), and 10) a layer which directly adjoins layer 9) and has a higher refractive index (HI layer) than layer 9) (LI layer). The layer system can be used for example as a surface reflector, preferably in applications using LEDs, in particular MCCOB for LEDs, as a solar reflector, or as a laser mirror, in particular for color wheels in DLP laser projectors. |
