Abstract: A sputtering system may include a substrate. The sputtering system may include at least one target. The at least one target may include at least one coating material to coat at least one layer onto the substrate. The at least one coating material may be sputtered onto the substrate in a presence of an inert gas. The inert gas may include argon gas and helium gas.

Abstract: In some implementations, an optical filter includes a first set of layers configured to pass light associated with a first wavelength range; a second set of layers configured to reflect light associated with at least one subrange of the first wavelength range; and a third set of layers configured to reflect light associated with a second wavelength range. In some implementations, the first wavelength range comprises an upper wavelength cutoff associated with a wavelength threshold, and the second wavelength range comprises a lower wavelength cutoff associated with the wavelength threshold. In some implementations, the optical filter includes a fourth set of layers configured to absorb a particular percentage of light in the first wavelength range.

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, 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.

Abstract: A bandpass filter may include a set of layers. The set of layers may include a first subset of layers. The first subset of layers may include hydrogenated germanium (Ge:H) with a first refractive index. The set of layers may include a second subset of layers. The second subset of layers may include a material with a second refractive index. The second refractive index may be less than the first refractive index.

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.
