| description | s sg cscs c gAn optical layered composite includes: a substrate having a front face, a back face, a thickness dbetween the front face and the back face and a refractive index n; and a coating applied to the front face. The coating comprises one or more coating layers. For at least one wavelength λin the range from 390 nm to 700 nm, the coating satisfies one of the following criterion: nn, and nis a mean refractive index of the coating layers, weighted by thickness; do is a total thickness of the coating; thicknesses are determined in a direction perpendicular to the front face; and k=λ/4π. |
