An optical construction includes a reflective polarizer and an optically diffusive film disposed on the reflective polarizer. The reflective polarizer includes an outer layer including a plurality of first particles partially protruding from a first major surface thereof to form a structured major surface. A first optically diffusive layer is conformably disposed on the structured major surface. The optically diffusive film includes a second optically diffusive layer including a plurality of nanoparticles dispersed therein, and a structured layer including a structured major surface. For a substantially normally incident light and a visible wavelength range from about 450 nm to about 650 nm and an infrared wavelength range from about 930 nm to about 970 nm, the second optically diffusive layer has an average specular transmittance Vs in the visible wavelength range and an average specular transmittance Is in the infrared wavelength range, where Is/Vs≥2.5.

Optical construction and display system

Diagnostic devices for quantitative or qualitative analysis of a sample fluid including an analyte include at least two portions made from a hydrophilic material. The planar portions are stacked on each other and each occupy a different and substantially parallel plane to form a three-dimensional structure. At least one of the planar portions includes a hydrophobic region formed by applying a low surface energy material that extends through a thickness of the substrate portion from a first major surface to a second major surface thereof. The hydrophilic regions in the overlying substantially parallel substrate portions can be aligned with each other such that a fluid is passively transported between adjacent hydrophilic regions to provide a sample flow path between adjacent substrate portions.
