Sensor window with a set of layers configured to a particular color and associated with a threshold opacity in a visible spectral range wherein the color is a color-matched to a surface adjacent to the sensor window

Abstract:

A sensor window may include a substrate and a set of layers disposed onto the substrate. The set of layers may include a first subset of layers of a first refractive index and a second set of layers of a second refractive index different from the first refractive index. The set of layers may be associated with a threshold transmissivity in a sensing spectral range. The set of layers may be configured to a particular color in a visible spectral range and may be associated with a threshold opacity in the visible spectral range.
