Abstract: A window for a sensing system is provided that includes: a substrate comprising an outer and an inner primary surface; an outer layered film disposed on the outer primary surface; and an inner layered film disposed on the inner primary surface. Each of the outer and inner layered films comprises alternating high index and low index layers. The outer layered film comprises a scratch resistant layer having a thickness from about 0.5 μm to about 10 μm, and exhibits a hardness of at least 11 GPa, as measured with a Berkovich Indenter Hardness Test. The window exhibits an average transmittance of greater than 85% within ±25 nm of at least one wavelength within the infrared spectrum from 900 nm to 1600 nm and an average transmittance of less than 5% in the visible spectrum from 420 nm to 650 nm, each at an angle of incidence

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: One or more aspects of the disclosure pertain to an article including a film disposed on a glass substrate, which may be strengthened, where the interface between the film and the glass substrate is modified, such that the article has an improved average flexural strength, and the film retains key functional properties for its application. Some key functional properties of the film include optical, electrical and/or mechanical properties. The bridging of a crack from one of the film or the glass substrate into the other of the film or the glass substrate can be suppressed by inserting a nanoporous crack mitigating layer between the glass substrate and the film.

Abstract: Embodiments of this disclosure pertain to articles that exhibit scratch-resistance and improved optical properties. In some examples, the article exhibits a color shift of about 2 or less, when viewed at an incident illumination angle in the range from about 0 degrees to about 60 degrees from normal under an illuminant. In one or more embodiments, the articles include a substrate, and an optical film disposed on the substrate. The optical film includes a scratch-resistant layer and an optical interference layer. The optical interference layer may include one or more sub-layers that exhibit different refractive indices. In one example, the optical interference layer includes a first low refractive index sub-layer and a second a second high refractive index sub-layer. In some instances, the optical interference layer may include a third sub-layer.

In one or more embodiments, the article exhibits an average transmittance of 85% or more, over the visible spectrum (e.g., 380 nm-780 nm). Embodiments of the optical film structure include aluminum-containing oxides, aluminum-containing oxy-nitrides, aluminum-containing nitrides (e.g., AlN) and combinations thereof. The optical film structures disclosed herein also include a transparent dielectric including oxides such as silicon oxide, germanium oxide, aluminum oxide and a combination thereof.
