Abstract:
A transparent sheet includes a texture in relief on a first of its main faces, such that, if n is the refractive index of the material including the texture, Pm is the mean slope in degrees of the textured face and Y(q) is the percentage of the textured surface with a slope greater than q/(n−1) in degrees, then the two cumulative conditions exist: Y(q)>3%+f(q) %*Pm*(n−1) and Y(q)>10%, with f(q)=24−(3*q) and q=2 or 3.
