TRANSPARENT SUBSTRATE COMPRISING ANTIGLARE COATING

摘要

A transparent substrate ( 6 ), comprising on at least one of its faces an antireflection coating, particularly at normal incidence made of a multilayer (A) of thin layers, characterized in that the multilayer comprises, in succession: a first layer (1), with a refractive index n₁ of between 1.8 and 2.2 and geometrical thickness e₁ of between 5 and 50 nm, a second layer (2), with a refractive index n₂ of between 1.35 and 1.65 and a geometrical thickness e₂ of between 5 and 50 nm, a third layer (3) with a refractive index n₃ of between 1.8 and 2.2 and a geometrical thickness e₃ of between 40 and 150 nm, a fourth layer (4) with a refractive index n₄ of between 1.35 and 1.65 and a geometrical thickness e₄ of between 40 and 150 nm,
