Abstract: A method comprising: filtering, by an optical filter, a first portion of an input optical signal with a first spectral range, wherein the first portion of the input optical signal is not passed through the optical filter and an optical filter structure; and passing, by the optical filter and an optical filter structure, a second portion of the input optical signal, with a second spectral range, through the optical filter and the optical filter structure and toward an optical sensor of a sensor system. The second portion of the input optical signal is used to provide an output electrical signal for the sensor system. The optical filter is a mixed dielectric/metal filter providing at least one of an angle shift of less than approximately 30 nm at angles of incidence from 0 degrees to 50 degrees, an angle shift of less than approximately 20 nm at angles of incidence from 0 degrees to 40 degrees, or an angle shift of less than approximately 10 nm at angles of incidence from 0 degrees to 20 degrees.

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: In some implementations, an optical interference filter (200) includes a substrate (210); and a set of layers (220) that are disposed on the substrate. The set of layers includes a first subset of layers (230), wherein the first subset of layers comprises an aluminum nitride (AlN) material, and wherein a stress of the first subset of layers is between -1000 and 800 megapascals; and a second subset of layers (240), wherein the second subset of layers comprises at least one other material (e.g. hydrogenated silicon).

Abstract: An optical device includes an optical sensor, a dye-based optical filter, and a multi-bandpass optical interference filter. The multi-bandpass optical interference filter is configured to pass a first spectral range of visible light, a second spectral range of visible light, and a third spectral range of visible light. The second spectral range does not overlap with the first spectral range, and the third spectral range does not overlap with the first spectral range and the second spectral range. The multi-bandpass optical interference filter is further configured to prevent passage of a fourth spectral range of near-infrared light. An angle shift associated with each spectral range, of the first spectral range, the second spectral range, and the third spectral range, is less than or equal to 2.0% of a center wavelength of the spectral range for angles of incidence between 0 and 30 degrees.

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.
