Abstract: An optical construction includes a lens layer and optically opaque first and second mask layers. The lens layer has a first major surface including a plurality of microlenses arranged along orthogonal first and second directions. The first and second mask layers are spaced apart from the first major surface and define respective pluralities of through first and second openings therein arranged along the first and second directions. The first mask layer is disposed between the structured first major surface and the second mask layer. There is a one-to-one correspondence between the microlenses and the first and second openings. The optical construction includes an intermediate layer disposed between the structured first major surface and the first mask layer and including an undulating second major surface facing, and in substantial registration with, an undulating third major surface of first mask layer so as to define a substantially uniform spacing therebetween.

Abstract: A curved optical film generally lying in a base plane and having a thickness of less than 500 microns, and an average optical absorption of less than 70% for unpolarized normally incident light in a predetermined wavelength range is described. A first cross-section of the optical film in a first plane perpendicular to the base plane has an actual first length AL1, a projected first length PL1, and a first stretch ratio S1 of (AL1?PL1)/PL1. A second cross-section of the optical film in a second plane perpendicular to the first and base planes has an actual second length AL2, a projected second length PL2, and a second stretch ratio S2 of (AL2?PL2)/P2. The optical film may have a maximum thickness variation of less than 20% along each of the first and second cross-sections, S1 may be at least 0.1, and S2 may be at least 0.01 and less than 0.8S1.

Abstract: A light control layer includes alternating transmissive and absorptive regions, along one or two dimensions. The light control layer may be substantially transparent, or have high transmission, for light incident at or near a normal angle to its surface, while absorbing light incident at angles away from normal. The height of the absorptive region, defined orthogonal to the local display surface, may be much greater than the width of the absorptive region resulting in a high aspect ratio structure. The width of the absorptive region may be relatively thin compared to the width of a pixel in a display. The light control layer may be applied to a display or incorporated into a display. The light control layer may be part of a film stack including other functional layers that cooperatively provide desirable optical properties.

The data storage disk molding processes produces replica disks having a surface relief pattern with replica lands and replica grooves. The method includes providing a master substrate. The master substrate is at least partially covered with a layer of photosensitive material. A surface relief pattern having master lands and master grooves is recorded in the data storage disk master, including the steps of exposing and developing the photosensitive material is controlled to form master grooves extending down to a substrate interface between the master substrate and the layer of photosensitive material, such that the width of the master grooves at the substrate interface corresponds to a desired width of the replica lands.
