    Abstract: Structured surface articles such as molds or sheeting are formed on a compound substrate including a machined substrate and a replicated substrate. In one embodiment, the structured surface is a cube corner element on a compound substrate. In another embodiment, the structured surface is a geometric structure that has a plurality of faces, where one face is located on the machined substrate and another face is located on the replicated substrate. In yet another embodiment, at least some of the faces include a compound face with a portion formed on the machined substrate and a portion formed on the replicated substrate. The method of making a structured surface article including a geometric structure having a plurality of faces includes forming an array of geometric structures in a first surface of a machined substrate; passivating selected locations of the first surface of the machined substrate; forming a replicated substrate of the machined substrate to form a compound substrate; forming an array of second geometric structures on a second surface opposite the first surface on the machined substrate; and removing selected portions from the second surface of the machined substrate.

    Abstract translation: 在包括机加工衬底和复制衬底的复合衬底上形成诸如模具或片材的结构化表面制品。 在一个实施例中，结构化表面是复合衬底上的立体角元件。 在另一个实施例中，结构化表面是具有多个面的几何结构，其中一个面位于加工衬底上，另一个面位于复制衬底上。 在另一个实施例中，至少一些表面包括具有形成在机加工衬底上的部分和形成在复制衬底上的部分的复合面。 制造包括具有多个面的几何结构的结构化表面制品的方法包括在加工的基底的第一表面中形成几何结构的阵列; 钝化加工基板的第一表面的选定位置; 形成所述加工基板的复制基板以形成复合基板; 在与加工的基底上的第一表面相对的第二表面上形成第二几何结构的阵列; 以及从加工的基板的第二表面移除所选择的部分。

    Abstract: A new technique for making cube corner elements that involves end milling is used in the fabrication of cube corner elements having non-orthogonal dihedral angles and dihedral angle errors, and arrays of such cube corner elements. A given optical face of a cube corner element may be a compound face with two constituent faces. In some cases, the constituent faces may be parallel and coplanar such that a given dihedral angle error pertains to the entire optical face, while in other cases, the two constituent faces may not be parallel, and may be associated with different dihedral angle errors.
