Zusammenfassung:Example systems may include one or both of a light emitter and a light receiver, and an optical filter. The optical filter may include a wavelength selective scattering layer configured to scatter visible light. The optical filter may include a wavelength selective reflecting layer having a predetermined transmission band configured to compensate for a color deviation. The optical filter may include a broadband reflecting layer having a predetermined reflection band configured to compensate for a color deviation. The optical filter may include a low-index layer configured to reduce a color deviation in light emitted by the light emitter or received by the light receiver. The wavelength selective scattering layer may include nanoparticles dispersed in a binder, wherein the ratio of the nanoparticles to the binder by weight is at least 50%. Example articles may include example optical filters.
