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.

Abstract: An optical filter may include a substrate, a first mirror that includes a first subset of layers of a set of layers, and a second mirror that includes a second subset of layers of the set of layers. The optical filter may include a spacer. The spacer may include a third subset of layers of the set of layers. The set of layers may include a plurality of high refractive index layers associated with a first refractive index and a plurality of low refractive index layers associated with a second refractive index that is less than the first refractive index. The optical filter may be associated with a spectral range from at least approximately 1200 nanometers (nm) to approximately 1900 nm.

Abstract: A spectrometer assembly is provided having an optical transmission filter including a stack of continuous, non-patterned alternating dielectric and metal layers. Angle-dependent transmission wavelength shift of the optical transmission filter with continuous metal layers is small e.g. in comparison with multilayer dielectric filters, facilitating size reduction of the spectrometer assembly.

Abstract: A device may include a filter array disposed on a substrate. The filter array may include a first mirror disposed on the substrate. The filter array may include a plurality of spacers disposed on the first mirror. A first spacer, of the plurality of spacers, may be associated with a first thickness. A second spacer, of the plurality of spacers, may be associated with a second thickness that is different from the first thickness. A first channel corresponding to the first spacer and a second channel corresponding to the second spacer may be associated with a separation width of less than approximately 10 micrometers (μm). The filter array may include a second mirror disposed on the plurality of spacers.

Abstract: An optical filter, a sensor device including the optical filter, and a method of fabricating the optical filter are provided. The optical filter includes one or more dielectric layers and one or more metal layers stacked in alternation. The metal layers are intrinsically protected by the dielectric layers. In particular, the metal layers have tapered edges that are protectively covered by one or more of the dielectric layers.
