OPTICAL ELEMENT WITH SAPPHIRE LAYER |
| 摘要 |
An optical element for a mobile apparatus comprising a layer of sapphire having a first refractive index value and comprising a surface, wherein the surface is visible to a user. The optical element further comprises a textured structure arranged on the surface of the layer of sapphire for affecting propagation of visible light incident upon the surface of the layer of sapphire, wherein the structure is configured to have a second refractive index value, the second refractive index value being lower than the first refractive index value, and wherein the textured structure is configured to reduce reflection of the visible light incident from the surface of the layer of sapphire. |
