Abstract: A film-based article including a release liner having first and second major sides, a film layer having first and second major sides, an adhesive layer disposed between the first major side of the release liner and the second major side of the film, wherein the adhesive layer comprises a first surface adjacent to the second major side of the film, and a second surface adjacent to the first major side of the release liner. The second surface of the adhesive layer comprises an irregular array of channels.

Abstract: In an example, an example article 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: 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.
