Abstract: A cover article is described herein that includes: a substrate comprising an outer and an inner primary surface, the outer and inner primary surfaces opposite of one another; and an optical film structure comprising an outermost surface disposed on the outer or inner primary surface of the substrate. The optical film structure comprises a plurality of alternating high refractive index and low refractive index layers. Each of the high index layers has a refractive index greater than a refractive index of each of the low index layers. Further, the cover article exhibits a substantially constant hue in reflectance with a D65 illuminant, as given by: (a) an exhibited color with a variation in Hue Angle (h*) of less than 60 degrees over a viewing angle range from 0 to 60 degrees; or (b) an exhibited grey hue or silver hue, each with a Chroma (c*) of less than 10.

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.
