    • The invention relates to a method and a mold for producing transparent optical elements from polymeric materials. In this case, the optical elements that can be produced in this way are intended to have at least surface regions which have reduced interfacial reflection. According to the invention, the procedure followed here is that, in the case of a reference element which consists of a polymeric material and corresponds to the respective optical element, the entire surface or a correspondingly selected surface is exposed to the influence of high-energy ions in a vacuum. In this way, an irregular nanostructure with alternately arranged elevations and depressions lying in between is formed on the corresponding surfaces. Subsequently, a thin electrically conducting layer is applied and electrochemical forming is carried out in order to obtain a mold with a negative contour which is superposed by the nanostructure. With such a mold, the optical elements can then be produced in a molding process of the nanostructure reducing the interfacial reflection.
    • 本发明涉及用于从聚合材料制造透明光学元件的方法和模具。 在这种情况下,可以以这种方式制造的光学元件旨在具有至少具有减小的界面反射的表面区域。 根据本发明,这里遵循的步骤是,在由聚合材料组成并对应于相应的光学元件的参考元件的情况下,整个表面或相应选择的表面暴露于高能量的影响 离子在真空中。 以这种方式,在相应的表面上形成具有位于其间的交替布置的高低差的不规则纳米结构。 随后,施加薄的导电层,并进行电化学形成以获得具有由纳米结构叠加的负轮廓的模具。 利用这种模具,可以在纳米结构的模制过程中制造光学元件,减少界面反射。
