Abstract: The disclosed light directing article has an optical element and a conformal retarder with predefined thickness that contours with the optical element. In one aspect, the light directing article is a retroreflective article, which further comprises a phase reversing optical reflector.

Abstract: A glass laminate including first and second glass layers, a reflective film having opposed first and second major surfaces and disposed between the first and second glass layers with the first and second major surfaces facing the respective first and second glass layers, a first adhesive layer disposed between and bonding together the first glass layer and the reflective film, and a second adhesive layer disposed between and bonding together the second glass layer and the reflective film is described. The second adhesive layer is thicker than the first adhesive layer such that the first major surface of the reflective film is separated from an outermost major surface of the first glass layer by a distance d1, the second major surface of the reflective film is separated from an outermost major surface of the second glass layer by a distance d2, and 0.05≤d1/d2≤0.9.

Abstract: Optical stacks including a first reflective polarizer and a partially reflective component are described. The partially reflective component may be a second reflective polarizer or a collimating reflector. The first reflective polarizer has a first average visible light reflectance for light polarized along the first block axis at normal incidence of at least 90 percent and a first average visible light transmittance for light polarized along the first pass axis at normal incidence of at least 85 percent. The second reflective polarizer has a second block axis and a second average visible light reflectance for light polarized along the second block axis at normal incidence being no more than the first average visible light reflectance minus 10 percent. The first and second block axes are not parallel and the first and second reflective polarizers have different f-ratios.
