摘要： Optical diffusing films are made by microreplication from a structured surface tool. The tool is made using a 2-part electroplating process, wherein a first electroplating procedure forms a first metal layer with a first major surface, and a second electroplating procedure forms a second metal layer on the first metal layer, the second metal layer having a second major surface with a smaller average roughness than that of the first major surface. The second major surface can function as the structured surface of the tool. A replica of this surface can then be made in a major surface of an optical film to provide light diffusing properties. The structured surface and/or its constituent structures can be characterized in terms of various parameters such as optical haze, optical clarity, Fourier power spectra of the topography along orthogonal in-plane directions, ridge length per unit area, equivalent circular diameter (ECD), and/or aspect ratio.
摘要翻译： 光学漫射膜通过微结构化表面工具进行制造。 该工具使用2部分电镀工艺制成，其中第一电镀工艺形成具有第一主表面的第一金属层，第二电镀工艺在第一金属层上形成第二金属层，第二金属层具有 平均粗糙度小于第一主表面的第二主表面。 第二个主表面可以作为工具的结构化表面。 然后可以在光学膜的主表面上制造该表面的复制品以提供光漫射性质。 结构化表面和/或其组成结构可以根据各种参数来表征，例如光学雾度，光学透明度，沿垂直面内方向的形貌的傅里叶功率谱，每单位面积的脊长度，等效圆直径（ECD） ，和/或纵横比。
