Transparent substrate with anti reflective coating

The transparent substrate (6), especially of glass, has an anti-reflective coating on at least one side made from four thin layers of dielectric materials, e.g. metal oxides, having alternate strong and weak refractive indices. The first and third layers (1, 3) have a high refractive index - between...

Beschreibung
Zusammenfassung:	The transparent substrate (6), especially of glass, has an anti-reflective coating on at least one side made from four thin layers of dielectric materials, e.g. metal oxides, having alternate strong and weak refractive indices. The first and third layers (1, 3) have a high refractive index - between 1.8 and 2.3, and the second and fourth have low refractive indices - between 1.3 and 1.7. The first and second layers are 5 - 50 nm thick; the third has a thickness of 100 - 120 nm, and the fourth between 80 and 90 nm.
