Abstract: An optical filter having a passband at least partially overlapping with a wavelength range of 800 nm to 1100 nm is provided. The optical filter includes a filter stack formed of hydrogenated silicon layers and lower-refractive index layers stacked in alternation. The hydrogenated silicon layers each have a refractive index of greater than 3 over the wavelength range of 800 nm to 1100 nm and an extinction coefficient of less than 0.0005 over the wavelength range of 800 nm to 1100 nm.

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 set of optical filter layers disposed onto a substrate. The set of optical filter layers may include a first subset of optical filter layers comprising a first material with a first refractive index. The first material may comprise at least silicon and hydrogen. The set of optical filter layers may include a second subset of optical filter layers comprising a second material with a second refractive index. The second material is different from the first material and the second refractive index is less than the first refractive index. The set of optical filter layers may include a third subset of optical filter layers comprising a third material different from the first material and the second material.

Abstract: In some implementations, an optical interference filter includes a substrate; and a set of layers that are disposed on the substrate. The set of layers includes a first subset of layers, wherein the first subset of layers comprises an aluminum nitride (AlN) material; and a second subset of layers, wherein the second subset of layers comprises a hydrogenated silicon (Si:H) material.

Abstract: A device may include one or more memories and one or more processors, communicatively coupled to the one or more memories, to receive design information, wherein the design information identifies desired values for a set of layers of an optical element to be generated during one or more runs; receive or obtain historic information identifying a relationship between a parameter for the one or more runs and an observed value relating to the one or more runs or the optical element; determine layer information for the one or more runs based on the historic information, wherein the layer information identifies run parameters, for the set of layers, to achieve the desired values; and cause the one or more runs to be performed based on the layer information.
