Abstract: A multilayer optical adhesive including a first viscoelastic or elastomeric adhesive layer and a second viscoelastic or elastomeric adhesive layer. A crosslinked or soluble resin layer may be disposed between the first viscoelastic or elastomeric adhesive layer and the second viscoelastic or elastomeric adhesive layer or the first viscoelastic or elastomeric adhesive layer may be immediately adjacent to the second viscoelastic or elastomeric adhesive layer. An interface between immediately adjacent layers is structured and there is a difference in refractive indices across the interface.

Abstract: The present disclosure describes a compact spotlight that can change the area which it illuminates. The spotlight incorporates a wide angle light source, a catadioptric lens, and a bearing system for moving the catadioptric lens, the light source, or both. Movement of the light source relative to the catadioptric lens along the optical axis can change the beam diameter of the spotlight, while providing an acceptable illumination pattern.

Abstract: The present disclosure provides a novel construction for homogenizing light in a mirror-lined light duct, in particular such as in a light duct having an increase in the cross-sectional duct area in the light propagation direction. The present disclosure also provides for an apparatus for light homogenization after a portion of the light in a duct has been extracted from the duct and/or diverted to a side duct.

Abstract: Window glass having sun-facing daylight redirecting optical structures with an embedded surface diffuser patterned on them. The optical structures are generally linear and formed from a repeating unit cell. Each unit cell has a base, two or more peaks opposite the base, and at least one curved side between the base and the peaks. The other sides between the base and the peaks can be substantially straight, curved, or a series of facets approximating a curve.

Abstract: Optical stacks including a grating structure that generates diffraction in two in-plane dimensions. The optical stacks may include two gratings, which may be one-directional or two-directional, or may include a single two-directional grating. The optical stacks include particles selected to give controlled diffusion of light. The optical stacks are suitable for reducing sparkle in displays.
