Abstract: An optical filter may include a first group of layers. The first group of layers may include alternating layers of a first dielectric material, of a group of dielectric materials, and a second dielectric material of the group of dielectric materials. The optical filter may include a second group of layers. The second group of layers may include alternating layers of a third dielectric material, of the group of dielectric materials, and a fourth dielectric material of the group of dielectric materials. The optical filter may include a third group of layers. The third group of layers may include alternating layers of a fifth dielectric material, of the group of dielectric materials, a sixth dielectric material, of the group of dielectric materials, and a metal material. The third group of layers may be disposed between the first group of layers and the second group of layers.

Abstract: An optical interference filter includes a substrate and a plurality of sets of layers that are disposed over the substrate. Each set of layers includes: a first layer that comprises at least a first oxide; a second layer disposed over the first layer that comprises at least a second oxide; and a third layer disposed over the second layer that comprises at least hydrogen and silicon. The optical interference filter may be configured to transmit light associated with a first spectral range (e.g., from 585 nanometers to 700 nanometers) and to block light associated with a second spectral range (e.g., from 440 nanometers to 475 nanometers). The third layer may have an extinction coefficient for the second spectral range that is greater than four times an extinction coefficient of the third layer for the first spectral range.

Abstract: An optical thin film filter may include a first set of filter layers with a first refractive index. The optical thin film filter may include a second set of filter layers with a second refractive index. A first set of thicknesses of the first set of filter layers, a second set of thicknesses of the second set of filter layers, the first refractive index, and the second refractive index may be configured to cause the optical thin film filter to achieve less than a threshold angle shift at a particular wavelength. The optical thin film filter may have an effective refractive index greater than or equal to 95% of a refractive index of a highest refractive index component material of the optical thin film filter.

Abstract: An optical filter may include a first mirror, a second mirror, and a spacer layer structure disposed between the first mirror and the second mirror. The spacer layer structure may include a first set of layers. Each layer, of the first set of layers, may be a first material associated with a first refractive index and a thickness that is greater than a layer thickness threshold. The spacer layer structure may include a second set of layers. Each layer, of the second set of layers, may be a second material associated with a second refractive index. Each layer, of the second set of, may be selected to replace a corresponding layer of the first material. The corresponding layer may be associated with a thickness that is less than the layer thickness threshold.

Abstract: According to an example, a first mirror layer may be formed on a substrate. A first set of spacer layers may be deposited on the first mirror layer to be positioned above a first group of the sensing elements and a second set of spacer layers may be deposited on the first mirror layer to be positioned above a second group of the sensing elements, in which the second set of spacer layers differs from the first set. In addition, a second mirror layer may be formed above the deposited first set of spacer layers and the deposited second set of spacer layers.
