  • Technique for determining presence of a species in a sample
    Patent number: 11802792
    Abstract: A technique of determining the presence of a species in a sample may include passing light through an optical filter. In an example, the optical filter may include a spatially variant microreplicated layer optically coupled to a wavelength selective filter. The wavelength selective filter may have a light incidence angle-dependent optical band. The spatially variant microreplicated layer may be configured to transmit light to a first optical region of the wavelength selective filter at a first predetermined incidence angle and to a second optical region of the wavelength selective filter at a second predetermined incidence angle.
    Type: Grant
    Filed: November 1, 2021
    Date of Patent: October 31, 2023
    Assignee: 3M INNOVATIVE PROPERTIES COMPANY
