See full text

An optical layered composite includes: 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 having two regions, the two regions being a region A and a region B. The region A comprises one or more coating layers, each of which satisfies one or both of the criteria: a thickness below 5 nm; or a refractive index of 1.6 or more. The region B comprises one or more coating layers, each of which satisfies one or both of the criteria: a thickness below 5 nm; or a refractive index below 1.6.
