    • An optical element includes a base, and primary structures and secondary structures disposed on a surface of the base, each of the primary structures and secondary structures being a projection or a depression. The primary structures constitute a plurality of rows of tracks on the surface of the base and are periodically repeatedly arranged at a fine pitch equal to or smaller than a wavelength of visible light. The secondary structures are smaller in size than the primary structures, and are provided between the primary structures, in the gaps in the arrangement of the primary structures, or on the surfaces of the primary structures.
    • 光学元件包括基座,以及设置在基座的表面上的主结构和次级结构,每个初级结构和次级结构都是突出部或凹陷部。 主要结构在基底的表面上构成多行轨道,周期性重复地以等于或小于可见光波长的细间距排列。 二级结构的尺寸小于初级结构,并且设置在主结构之间,主结构的间隙中或主结构的表面上。
