Abstract: Methods of manufacture of an optical diffuser. In one embodiment, an optical diffuser is formed by providing a wafer including a silicon slice of which an upper face is covered with a first layer made of a first material itself covered with a second layer made of a second selectively etchable material with respect to the first material. The method further includes forming openings in the second layer extending up to the first layer and filling the openings in the second layer with a third material. The method yet further includes bonding a glass substrate to the wafer on the side of its upper face and removing the silicon slice.

Abstract: The present invention relates to digital pathology, and relates in particular to a digital pathology scanner illumination unit. In order to provide digital pathology scanning with improved illumination, a digital pathology scanner illumination unit (10) is provided that comprises a light source (12), a light mixing chamber (14), and a light diffuser (16). The light source comprises a plurality of light elements (18) that are arranged longitudinally along a linear extension direction. The mixing chamber comprises a transparent volume (22) providing a mixing distance (DM) between the plurality of the light elements and the light diffuser such that light with a uniform intensity is provided at a downstream edge (26) of the mixing chamber; and the mixing chamber is arranged, in terms of light propagation, between the plurality of the light elements and the light diffuser. Further, the light diffuser comprises a diffusing material such that the light is transformed into light that has uniformity at different angles, in particular low angles.

Abstract: Disclosed herein are methods for forming light-transmitting articles comprising depositing a layer comprising a second material on a substrate comprising a first material, and forming a patterned surface on the second material. The first and second materials can have different glass transition temperatures Tg and/or refractive indices n. Additional layers comprising a third material can also be formed over the patterned surface, the third material having a glass transition temperature Tg and refractive index n that may be the same or different from those of the first and second material. Light-transmitting articles formed by such methods, as well as display devices comprising such light-transmitting articles are also disclosed herein.

Abstract: Disclosed herein is a display device including a reflection type image display portion having a sheet-like anisotropic scattering member. In an area, in an in-plane direction, of the anisotropic scattering member, a low-refractive index area and a high-refractive index area are disposed in a mixture style. The anisotropic scattering member is disposed so that a light is scattered when an outside light is made incident from a surface side on which a degree of a change in a refractive index in a vicinity of a boundary between the low-refractive index area and the high-refractive index area is relatively large, and is emitted from a surface side on which the degree of the change in the refractive index in the vicinity of the boundary between the low-refractive index area and the high-refractive index area is relatively small.
