Abstract

See full text

Disclosed is an optical article including a substrate having a front main face and a rear main face, the rear main face being coated with a multilayer antireflection coating. The outermost layer of the multilayer antireflection coating is a layer A containing silicon, carbon and fluorine atoms, the layer A having a refractive index lower than or equal to 1.45 and a thickness higher than or equal to 20 nm. The mean light reflection factor Rv on the rear main face between 380 nm and 780 nm is lower than or equal to 1.5%. The mean reflection factor Ruv on the rear main face between 280 nm and 380 nm, weighted by the function W (2) defined in the ISO 13666:1998 standard, is lower than or equal to 7%, for an angle of incidence of 35°.
