A compound reflective plate includes a metal base and a reflective film. The metal base includes a reflective surface. The reflective film is covering the reflective surface. The reflective film includes colloidal transparent substrate, reflective particles, and diffusion particles. A surface of the reflective film opposite to the metal base is a rough, irregular, and curved surface. A mass ratio of the diffusion particles to the sum of the colloidal transparent substrate and the reflective particles ranges from 0.05 to 0.07. A mass ratio of the reflective particles to the colloidal transparent substrate ranges from 0.25 to 0.54.

A multilayer coating has a substrate, an optical layer, and a buffer layer between the substrate and the optical layer. The buffer layer has a coefficient of thermal expansion between that of the substrate and the optical layer. The multilayer coating has properties that enable its use in deep ultraviolet (DUV) wavelengths, such as for a multilayer mirror or edge filter. This multilayer coating with a buffer layer provides improved thermal stability and lifetime.

A laminated film having a resin layer laminated on at least one surface of a base film. The laminated film is characterized by: the base film being a semi-aromatic polyamide film that has been at least uniaxially stretched; the resin layer having a thickness of 0.03 to 0.5 μm; and the close adhesion between the base film and the resin layer, according to the cross-cut method described in JIS K 5600, being 95% or more.

A method for producing an optical component of a lighting device for vehicles, wherein a base body is made of a translucent or transparent material, a screen coating is applied to an outer surface of the base body by vapor deposition or by sputtering of a coating material, wherein the screen coating is applied as a reflective coating, wherein, during the application process, first a first reflective laminate layer with a low degree of reflection and then a second reflective laminate layer with a high degree of reflection are applied.

Method and apparatus for producing metal-coated optical fiber involves providing a length of optical fiber having a glass fiber with or without a carbon layer surrounded by a liquid-soluble polymeric coating. The optical fiber is passed through a series of solution baths such that the fiber will contact the solution in each bath for a predetermined dwell time, the series of solution baths effecting removal of the polymer coating and subsequent electroless plating of metal on the glass fiber. The optical fiber is collected after metal plating so that a selected quantity of the metal-coated optical fiber is gathered, Preferably, the glass fiber passes through the series of solution baths without contacting anything except for the respective solution in each.

A substrate and manufacturing method therefor, a display panel, and a display device. The substrate comprises a substrate base; and a first organic film and a second organic film which are located on the substrate base, wherein the first organic film and second organic film are used as a flat layer, and the refractive index of the first organic film is different from that of the second organic film. The first organic film and the second organic film are constructed such that after incident light obliquely incident on the substrate passes through the first organic film and the second organic film, emergent light of the incident light is deflected to the direction away from the substrate.
