A reflector element and a method for manufacturing a reflector element are disclosed. In an embodiment the reflector element includes a plastic substrate and a silver layer arranged on the plastic substrate. The reflector element further includes a first barrier layer arranged on the silver layer, wherein the barrier layer has an at least 15 nm-thick oxide layer and a second barrier layer arranged on the first barrier layer, wherein the barrier layer includes siloxane, and wherein a thickness of the second barrier layer is at least 250 nm and at most 450 nm.

Reflector element and a method for manufacturing same

A method for producing a reflector element and a reflector element are disclosed. In an embodiment the method includes depositing a layer sequence on a substrate, wherein the layer sequence includes at least one mirror layer and at least one reactive multilayer system and igniting the reactive multilayer system in order to activate heat input in the layer sequence.

Method for producing a reflector element and reflector element

An optical element including a reflective coating is disclosed. In an embodiment the reflective coating includes an adhesion-promoting layer, an at least partially reflective silver layer disposed on the adhesion-promoting layer and a protective layer system disposed on the silver layer, wherein the protective layer system includes a plurality of dielectric layers, wherein the dielectric layers include at least one first layer and at least one second layer, wherein the first layer and the second layer have a different resistance to at least two different contamination substances, wherein the dielectric layers have a thickness of not more than 30 nm, and wherein a number of the dielectric layers amounts to at least five.
