Zusammenfassung: | 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. |
