Beschreibung
Zusammenfassung:	A system such as a vehicle system, building, or electrical equipment may be provided with one or more optical components. The optical components may include a near-infrared camera or other components that operate at near-infrared wavelengths. A visible-light-reflecting-and-infrared-light-transmitting layer may overlap the optical component. The visible-light-reflecting-and-infrared-light-transmitting layer may have an infrared-transparent substrate. A polymer layer may be formed on the substrate and may contain plasmonic nanoparticles that reflect white light. Colorant may be incorporated into the polymer layer or into an additional polymer coating to impart a desired color to the reflected white light and thereby provide the visible-light-reflecting-and-infrared-light-transmitting layer with a desired appearance.
