Abstract: A low density substrate material for reflecting optics. The substrate material is a magnesium alloy or composite material that is capable of being finished by diamond turning to form an optically smooth surface with low root-mean-square roughness. The finish quality of the diamond-turned surface is sufficiently good to permit use of the magnesium material as a substrate for a reflecting optic without further processing. The magnesium substrate material contains at least 80 wt % Mg and may also include Al, Si and/or other elements. The density of the magnesium substrate material is much lower than the density of current Al alloy substrate materials.

Abstract: An optical element can include a substrate comprising a Group VIA or fluoride-based non-oxide material and an adhesion layer disposed directly on the substrate. An anti-reflective coating stack is disposed directly on the adhesion layer. Methods for forming an optical element are also provided. The density and stress of the adhesion layer and layers of the anti-reflective coating stack are controlled to provide corrosion-resistant coatings on Group VIA or fluoride-based non-oxide substrates. Preferred substrate materials are materials that exhibit high transparency in the infrared.

Abstract: A method for coating substrates is provided. The method includes diamond turning a substrate to a surface roughness of between about 60 Å and about 100 Å RMS, wherein the substrate is one of a metal and a metal alloy. The method further includes polishing the diamond turned surface of the substrate to a surface roughness of between about 10 Å and about 25 Å to form a polished substrate, heating the polished substrate, and ion bombarding the substrate with an inert gas. The method includes depositing a coating including at least one metallic layer on the ion bombarded surface of the substrate using low pressure magnetron sputtering, and polishing the coating to form a finished surface having a surface roughness of less than about 25 Å RMS using a glycol based colloidal solution.

Abstract: An optical element based on a graphite substrate is provided. The optical element may be a reflective element and may include a finishing layer, adhesion layer, and/or galvanic compatibility layer. Finishing layers include Ni and Si and provide a surface that can be processed to a low finish to support a reflective layer or reflective stack. Graphite substrates are light weight, are amenable to diamond turning and can be machined to near net shape, have low coefficients of thermal expansion to enable operation over wide temperature ranges, and have high chemical stability.

Abstract: The disclosure is directed to a highly reflective multiband mirror that is reflective in the VIS-NIR-SWIR-MWIR-LWIR bands, the mirror being a complete thin film stack that consists of a plurality of layers on a selected substrate. In order from substrate to the final layer, the mirror consists of (a) substrate, (b) barrier layer, (c) first interface layer, (d) a reflective layer, (e) a second interface layer, (f) tuning layer(s) and (g) a protective layer. In some embodiments the tuning layer and the protective layer are combined into a single layer using a single coating material. The multiband mirror is more durable than existing mirrors on light weight metal substrates, for example 6061-Al, designed for similar applications. In each of the five layer types methods and materials are used to process each layer so as to achieve the desired layer characteristics, which aid to enhancing the durability performance of the stack.
