Optical component with scratch-resistant anti-reflection coating and method for producing same

An optical component 10 comprises a substrate 1 provided with a layer stack 2 including a plurality of successive layers of different materials and different refractive indices (RIs), which defines an anti-reflection coating, wherein the layers of the layer stack 2 contain at least one layer of each of a first 4, second 3, and third 5 material types, with at least three different refractive indices. A layer of the first type has a higher RI than a layer of the second type, and a layer of the third type has a lower RI than a layer of the second type; wherein the uppermost layer 7 is a layer of the second type 3 and the second uppermost layer is a layer of the first type 4 and wherein the layer stack 2 includes at least one further layer which is disposed below the two uppermost layers within the layer stack 2 and which is a layer of the third type 5.
