Title
(EN) Article comprising a mesoporous coating having a refractive index profile and methods for making same
(ZH) 包括具有折射率分布的中孔涂层的制品,及其制备方法
Abstract
(EN)
The invention concerns an article comprising a substrate having a main surface covered with a coating part of which at least is mesoporous and has a refractive index profile with optical function, the variation of which is imposed by the mesopore content and/or the filling factor of the mesopores. The profile may be such that the refractive index varies depending on the distance to a given axis, or such that the refractive index variation is monotone decreasing along any axis perpendicular to the surface of the substrate underlying the mesoporous part of said coating and oriented away from the substrate. The invention also concerns methods for making said articles, which differ depending on the technique from which the refractive index profile is created. The invention is applicable to ophthalmological optics.

本发明涉及一种包括具有由涂层涂覆的主表面的基底的制品,部分该涂层至少是中孔性的且具有带有光学功能的折射率分布,其变化由中孔含量和/或中孔的填充率施加。该分布可以是使得折射率依据在特定轴向上的距离而变化,或者使得折射率变化是单调的,沿着垂直于在所述涂层的中孔部分下面的基底的表面且远离该基底定向的任何轴降低。本发明还涉及制备所述制品的方法,其依据形成该折射率分布的技术而不同。本发明可应用于眼科光学器件。
