Abstract: A window for a sensing system includes a first layered film and a second layered film. The first and second layered film each include alternating layers of lower and higher refractive index materials. The first layered film includes a scratch resistant layer such that the window exhibits a maximum nanoindentation hardness of greater than or equal to 10 GPa when indented on the first layered film. The materials and thicknesses of the layers of the first and second layered films are selected such that the window exhibits relatively high transmittance and low reflectance in two distinct wavelength ranges of interest.

Abstract: Disclosed is a window for a sensing system comprising a substrate, a first layered film comprising alternating layers of higher and lower index materials, and a second layered film comprising alternating layers of higher and lower index materials. The window comprises a maximum hardness, measured at the first layered film and by the Berkovich Indenter Hardness Test, of at least 8 GPa. The first and second layered films are configured so that the window has favorable antireflective and transmission attributes in an infrared wavelength range of interest, while providing relatively low reflectance and transmittance in the visible spectrum to provide a dark appearance and low signal noise.

Abstract: An article is described herein that includes: a translucent substrate having a major surface; and an anti-reflective coating disposed on the major surface and forming an anti-reflective surface. The article exhibits a single side average photopic light reflectance at the anti-reflective surface of less than 0.35%. Further, the article exhibits a single side color shift (ΔC) of less than 6 over an incident angle range from 0 degrees to 60 degrees incidence at the anti-reflective surface, wherein the anti-reflective coating comprises a physical thickness from about 50 nm to less than 500 nm. In addition, the anti-reflective coating comprises a plurality of layers that comprises at least one low refractive index layer and at least one high refractive index layer. Further, each high refractive index layer has a refractive index of greater than 2.0 and each low refractive index layer has a refractive index of less than 1.7.
