1. An optical layered composite, comprising:
a substrate having a front face, a back face, a thickness ds between the front face and the back face and a refractive index ns; and
a coating applied to the front face, the coating comprising one or more coating layers, wherein, for at least one wavelength λg in the range from 390 nm to 700 nm, the coating satisfies one of the following criterion:
wherein nc is a mean refractive index of the coating layers, weighted by thickness, wherein dc is a total thickness of the coating, wherein thicknesses are determined in a direction perpendicular to the front face, and wherein k=λg/4π, wherein a total thickness variation is less than 2 μm, wherein the optical layered composite is configured to transversely propagate light introduced into the optical layered composite.
