  • Publication number: 20230012033
    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.

  • Publication number: 20230001733
    Abstract: A user device may cause light to be emitted at a security article by one or more light emission devices of the user device. The user device may obtain from a first set of one or more optical sensor devices of the user device first sensor data associated with the security article, and may obtain from a second set of one or more optical sensor devices of the user device second sensor data associated with the security article. The user device may determine, based on the first sensor data and the second sensor data, one or more characteristics of a security feature of the security article. The user device may determine, based on the one or more characteristics of the security feature, whether the security article is authentic. The user device may cause, based on determining whether the security article is authentic, one or more actions to be performed.

  • Publication number: 20210238733
    Abstract: A sputtering system may inject hydrogen and a sputtering gas into a chamber of the sputtering system, which may cause at least one layer of a hydrogenated semiconductor material, such as hydrogenated silicon (Si:H), to be sputtered onto a substrate disposed in the chamber until the at least one layer has a thickness that satisfies a threshold. In some implementations, the hydrogen and the sputtering gas may be injected into the chamber of the sputtering system while a temperature in the chamber is in a range from 145 degrees Celsius to 165 degrees Celsius. Accordingly, in some implementations, the sputtered layer of the hydrogenated semiconductor material may have one or more optical properties that satisfy a threshold to enable operation in a 9xx nanometer wavelength regime and at larger wavelengths.
