Publication number: 20070118939Abstract: A substrate made of transparent material having a surface presenting a regular and orderly distribution of reliefs or cavities of nanometric dimensions is obtained with a method including the depositing of a layer of aluminium on the substrate made of transparent material, and subsequent operations of anodization of the aluminium in order to obtain an alumina structure with an orderly distribution of pores according to a pattern that is transferred onto the surface of the transparent substrate. The alumina can be used as sacrificial layer or else can remain as forming an integral part of the finished product. The method is performed in such a way as to obtain cavities or reliefs sized and arranged so as to bestow upon the transparent substrate anti-reflection properties, so as to increase the percentage of radiation transmitted by the transparent substrate at the wavelengths at which said anti-reflection properties are manifested.Type: ApplicationFiled: November 9, 2006Publication date: May 24, 2007Applicant: C.R.F.
