Abstract: A light control film includes a two-dimensional array of projections arranged across the light control film. A square of a magnitude of a Fourier transform frequency spectrum of the projections includes an annular continuous peak and a corresponding annular continuous full width (FW) at 15% maximum. The peak and the FW vary by no more than about respective factors of 10 and 3 along the annular continuous peak.

Abstract: The present disclosure is directed to reflective microstructures where at least part of the reflective surface of the microstructure is radially symmetric around a given axis. The disclosure is also directed to articles comprising the reflective microstructures.

Abstract: A light control film includes a two-dimensional array of projections arranged across the light control film. A square of a magnitude of a Fourier transform frequency spectrum of the projections includes a plurality of distinct peaks separated by one or more valleys. The peaks and the one or more valleys have respective averages Pavg and Vavg, Pavg/Vavg?5, such that when light from a substantially Lambertian light source is incident on the light control film, the light control film transmits the incident light with the transmitted light propagating along a transmission axis and having an intensity profile having a full width at half maximum of less than about 120 degrees in each cross-section of the intensity profile that comprises the transmission axis.
