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 cover glass article is described herein comprising at least one substrate with opposing outer and inner primary surfaces, and at least one of an outer optical film structure and an inner optical disposed on the outer and inner primary surfaces, respectively. The outer and inner film structures comprise alternating high and low refractive index layers, in which at least a portion of the high refractive index layers independently is an oxide, a nitride, and/or an oxynitride, and at least a portion of the low refractive index layers independently is an oxide, a nitride, an oxynitride, and/or a metal fluoride. The cover glass article exhibits high visible light transmittance and low infrared light transmittance, being useful in applications including lenses, sensors, sensor assemblies, light sources, smartwatches, a smartphones, smart glasses, vehicle camera systems, displays, and cameras.
