Optical layered composite having a coating thickness below a threshold and its application in augmented reality
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 comprises one or more coating layers. For at least one wavelength λg in the ran...

| Zusammenfassung: | 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 comprises one or more coating layers. For at least one wavelength λg in the range from 390 nm to 700 nm, the coating satisfies one of the following criterion: ncns, anddc |
