Abstract: The present disclosure describes a protective coating for a low index material, and a process for preparing a protected low index material. The protective coating partially penetrates the pores of a low index material, providing a seal protecting the pores, and can strengthen the construction by forming a gradient in properties of the protected low index material. The present disclosure further provides a diffusing low index optical element having a protected low index material and a diffusing layer disposed on the low index material.
Abstract translation: 本公开描述了用于低折射率材料的保护涂层以及用于制备受保护的低折射率材料的方法。 保护涂层部分地渗透低折射率材料的孔隙，提供保护孔隙的密封，并且可以通过形成受保护的低折射率材料的性质的梯度来加强结构。 本公开还提供了一种具有受保护的低折射率材料和设置在低折射率材料上的漫射层的扩散低折射率光学元件。

Abstract: System and technique for inspecting a moving film by measuring the levels of light transmission through a thickness dimension of the film are described. The system includes a light source configured to provide light including a particular wavelength, or a particular range of wavelengths. The light from the light source is directed toward a first surface of the film, and an image capturing device is located adjacent to the light source on a second side of the film opposite the first surface, the image capturing device configured to measure the levels of light intensity exiting a second surface of the film. Measurements of the level of the light intensity passing through the film may be spatially synchronized to physical positions along the film to generated at least one roll map indicative of light transmission characteristics of the film over the imaged portions of the film.
