HARD ANTI-REFLECTIVE COATINGS AND MANUFACTURING AND USE THEREOF |
| 摘要 |
A coated substrate is provided with a scratch-resistant anti-reflective coating. The anti-reflective coating is designed as an optical interference coating that has at least two low refractive index layers and at least one high refractive index layer. The high refractive index layer is a transparent hard material layer and includes crystalline aluminum nitride with a hexagonal crystal structure with a (001) preferred orientation. The low refractive index layers include SiO2. The low refractive index layers and high refractive index layers are arranged alternately. |

1. A coated substrate comprising:
a substrate; and an anti-reflective coating designed as an optical interference coating including at least two low refractive index layers and at least one high refractive index layer, the high refractive index layer being a transparent hard material layer that comprises crystalline aluminum nitride having a hexagonal crystal structure exhibiting a predominant (001) preferred orientation, wherein the at least two low refractive index layers include SiO2, and wherein the high refractive index layer is disposed between the at least two low refractive index layers. |
