    • This transparent layered element (1) has two smooth outer main surfaces (2A, 4A) and comprises: two outer layers (2, 4), which each form one of the two outer main surfaces (2A, 4A) of the element (1) and which are constituted of dielectric materials having substantially the same refractive index (n2, n4), and a central layer (3) inserted between the two outer layers, this central layer (3) being formed either by a single layer which is a dielectric layer having a refractive index different from that of the outer layers or a metal layer, or by a stack of layers which comprises at least one dielectric layer having a refractive index different from that of the outer layers or a metal layer. Each contact surface (S0, S1) between two adjacent layers of the element (1), which are one a dielectric layer and the other a metal layer, or which are two dielectric layers having different refractive indices, is textured and parallel to the other textured contact surfaces.
    • 该透明分层元件(1)具有两个平滑的外主表面(2A,4A),并包括:两个外层(2,4),每个形成元件(1)的两个外主表面(2A,4A)中的一个 ),其由具有基本上相同折射率(n2,n4)的介电材料和插入在两个外层之间的中心层(3)构成,该中心层(3)由单层形成,该层是 电介质层的折射率不同于外层或金属层的折射率,或通过一叠层,其包括折射率不同于外层或金属层的至少一个电介质层。 元件(1)的两个相邻层之间的每个接触表面(S0,S1)是电介质层,另一个是金属层,或者是具有不同折射率的两个介电层,它们被纹理化并平行于另一个 纹理接触面。
