Entspiegelungsschicht sowie Verfahren zur Herstellung derselben

The coating comprises a support layer of optically transparent material which has an upper surface with anti-reflective property regarding the radiation wave lengths shining on the surface. The anti-reflective surface side has a superficial roughness with randomly distributed macrostructures. The macrostructures with surface structures of a periodic origin - so-called microstructures - are additionally modulated by the periodic lengths being less than the wave lengths of the radiation incident on the anti-reflective surface. ADVANTAGE - Combines reflection properties of anti-glare layers with sub-wave length gratings. The superimposition of macrostructures on microstructures on one optical surface prevents discrete reflection images and the reduces the proportion through hemispherical reflection
