Object with reflection-reducing coating and method for the production thereof

An object with a reflection-reducing coating, comprising:

• a substrate;
• and
• a coating arranged on the substrate,
• wherein the coating is multilayered and comprises:
• an outer layer having a refractive index n1;
• and
• at least one second sub-layer with a refractive index n2 which is adjacent to the outer layer,
• wherein n2>n1+0.4, and
• wherein the outer layer possesses a refractive index n1>1.50 and a layer hardness greater than 8 GPa.

An object with reflection-reducing coating, comprising:

• a substrate;
• and
• a coating arranged on the substrate,
• wherein the coating comprises at least one multilayer outer layer comprising a first material with a refractive index n1 and a second material with a refractive index n2,
• wherein the multilayer outer layer comprises a nanolaminate of the first and the second materials, wherein n2>n1+0.4, and
• wherein the multilayer outer layer possesses a refractive index n1>1.46, and a layer hardness of greater than 8 GPa.
