Abstract: The present disclosure generally relates to patterned gradient polymer films and methods for making the same, and more particularly to patterned gradient optical films that have regions that include variations in optical properties such as refractive index, haze, transmission, clarity, or a combination thereof. The variation in optical properties can occur across a transverse plane of the film as well as through a thickness direction of the film.

Abstract: A system may include one or both of a light emitter and a light receiver, and an optical filter. The optical filter includes a wavelength selective scattering layer. The wavelength selective scattering layer may have a near-infrared scattering ratio of less than about 0.9. The filter may have a visible reflective haze ratio of greater than about 0.5. A method may include disposing the wavelength selective scattering layer adjacent one or both of the light emitter and the light receiver. The optical filter may include a wavelength selective reflective layer. The optical filter may include a wavelength selective absorbing layer. An article may include the optical filter. The wavelength selective scattering layer may have an average near-infrared scattering of less than 60%, an average visible scattering of greater than 10%, and a difference between the % total visible reflectance and the % diffuse visible reflectance of less than 20.

Abstract: The disclosed patterned wavelength-selective material and process for making the patterned wavelength-selective material uses patterned applied adhesive and a structurally weak wavelength-selective material that includes portions that contact the adhesive and break to remain in contact with the adhesive. In one embodiment, the wavelength-selective material comprises an array of sections with cuts at least partially through a wavelength-selective film at each section secured to the adhesive. In another embodiment, the wavelength-selective film comprises a transfer stack of layers.

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.

Abstract: Example systems may include one or both of a light emitter and a light receiver, and an optical filter. The optical filter may include a wavelength selective scattering layer configured to scatter visible light. The optical filter may include a wavelength selective reflecting layer having a predetermined transmission band configured to compensate for a color deviation. The optical filter may include a broadband reflecting layer having a predetermined reflection band configured to compensate for a color deviation. The optical filter may include a low-index layer configured to reduce a color deviation in light emitted by the light emitter or received by the light receiver. The wavelength selective scattering layer may include nanoparticles dispersed in a binder, wherein the ratio of the nanoparticles to the binder by weight is at least 50%. Example articles may include example optical filters.
