Method for the production of stretchable and deformable optical elements, and elements thus obtained

摘要

It is described a method for the production of a fully or partially reflective stretchable and deformable optical element, comprising the implantation in at least one surface of an elastomeric support, by a technique of“Cluster Beam Implantation”, of neutral nanoclusters of a material selected among one or more metals, their alloys, their oxides or mixtures thereof, thus obtaining in said support a nanocomposite layer, possibly emerging at the surface of said element, and said implantation taking place by: uniformly implanting said nanoclusters in a surface of said elastomeric support, wherein said surface has a molded profile essentially corresponding to the profile of the optical element to be produced; or selectively implanting said nanoclusters in a flat surface of said elastomeric support; or uniformly implanting a first layer of said nanoclusters in a surface of said elastomeric support, and then selectively implanting a second layer of said nanoclusters onto the first nanoclusters layer thus obtained.
