Title
(EN) Transparent substrate comprising antiglare coating
(ZH) 包含减反射涂层的透明基材
Abstract
(EN)
The invention concerns a transparent substrate (6) comprising on at least one of its surfaces an antiglare coating, in particular with normal incidence consisting of a stack (A) of thin films. The invention is characterized in that the stack successively comprises: one first film (1) of refractive index n1 ranging between 1.8 and 2.2 and of geometric thickness e1 ranging between 5 and 50 nm, a second film (2) of refractive index n2 ranging between 1.35 and 1.65 and of geometric thickness e2 ranging between 5 and 50 nm, a third film (3) of refractive index n3 ranging between 1.8 and 2.2 and of geometric thickness e3 ranging between 40 and 150 nm, a fourth film (4) of refractive index n4 ranging between 1.35 and 1.65 and of geometric thickness e4 ranging between 40 and 150 nm.
