| 摘要 |
The invention relates to coated optical elements, coatings therefor and methods of producing such coatings, the coatings having improved characteristics of adhesion and of resistance to abrasion. In a preferred embodiment the coating includes a plurality of superimposed layers, namely: a hardcoat layer, a thin adhesion layer, a first dielectric layer including a material having a high refraction index selected from the group comprising: CrxOy, TiO2, ZnSe, ZnS and mixtures thereof, wherein x is a number comprised between 1 and 2 and y is a number comprised between 1 and 3; and a second dielectric layer having a refraction index lower than the refraction index of the second material.
