Optical article having a temperature-resistant anti-reflection coating with optimized thickness ratio of low index and high index layers |
| abstract |
The present invention relates to an optical article having anti-reflection properties and high thermal resistance, comprising a substrate having at least one main face coated with a multi-layer anti-reflection coating comprising a stack of at least one high refractive index layer and at least one low refractive index layer, wherein the ratio:RT sum of the physical thicknesses of the low refractive index layers of the anti-reflection coating/sum of the physical thicknesses of the high refractive index layers of the anti-reflection coating is higher than 2.1. If the anti-reflection stack comprises at least one low refractive index layer having a physical thickness ≥100nm which is not the outermost layer of the anti-reflection coating, said relatively thick layer and the underlying layers are not taken into account in RT calculation. |
