Abstract:
The present invention relates to an optical article having anti-reflection properties and high thermal resistance, comprising a substrate having at least one main face coated with a multi-layer anti-reflection coating comprising a stack of at least one high refractive index layer and at least one low refractive index layer, wherein the ratio:R T sum of the physical thicknesses of the low refractive index layers of the anti-reflection coating/sum of the physical thicknesses of the high refractive index layers of the anti-reflection coating is higher than 2.1. If the anti-reflection stack comprises at least one low refractive index layer having a physical thickness =100nm which is not the outermost layer of the anti-reflection coating, said relatively thick layer and the underlying layers are not taken into account in R T calculation.

Abstract:
A distribution mask including at least two separate blanking panels (22), one of which is mounted mobile. The two blanking panels (22) are substantially coplanar, and, controlled by a common control unit (23), both mounted continuously mobile between two extreme positions, namely, a close position, and for which the space (E) between them is minimal, and a spaced position, for which the space (E) is on the contrary at its maximum. The invention is particularly applicable to antiglare treatment of ophthalmic lenses.
