摘要： A nanovoided spacer material that is used as a mechanical buffer between at least two optical components. The optical components may include gratings (e.g., Bragg gratings, moth-eye surfaces, etc.) having sensitive and fragile surfaces (e.g., patterned surfaces). The nanovoided spacers may have a predetermined thickness and concentration of nanovoids to provide a given optical property (e.g., a reflection coefficient at an interface between two optical elements). The nanovoided spacer may include a multilayer structure (e.g., two or more layers) of varying refractive index (e.g., to reduce reflections between surfaces of the optical elements). The nanovoided spacer may include from about 10% to 90% nanovoids by volume and may have an average index of refraction of about 1.15. Various other methods, systems, apparatuses, and materials are also disclosed.

摘要： Gloss of a surface having a concave-convex structure is measured, and R/V, which is a ratio of a diffuse specular reflection intensity R to a sum total V of diffuse reflection intensities (in formula, the diffuse specular reflection intensity R represents a diffuse reflection intensity measured at an aperture angle of 1 degree by a variable-angle photometer in a diffuse specular reflection direction when visible light is radiated, at an angle of 45 degrees from a normal line, to the surface having the concave-convex structure of the anti-glare film, and the sum total V of diffuse reflection intensities represents a sum total of diffuse reflection intensities measured at an aperture angle of 1 degree by a variable-angle photometer for every 1 degree from −45 degrees up to 45 degrees, including 0 degrees, with respect to the diffuse specular reflection direction when visible light is radiated, at an angle of 45 degrees from a normal line, to the surface having the concave-convex structure of the anti-glare film), is evaluated to manufacture an anti-glare film. The above-described method enables an anti-glare film having high anti-glare properties and high contrast to be manufactured at high productivity.

摘要： The present disclosure provides a method for manufacturing a diffusion cover that diffuses and transmits light from a semiconductor light-emitting element. The method includes the steps of preparing a base member having an obverse surface and a reverse surface that face away from each other in a thickness direction; forming a lens material on the obverse surface, the lens material containing a photosensitive transparent resin; and removing a portion of the lens material by performing grayscale exposure and development, and forming a lens having a plurality of lens members. Such a configuration can provide a diffusion cover suitable for reducing the manufacturing cost.

摘要： A process of making a diverging-light fiber optics illumination delivery system includes providing a micro-post comprising a glass-ceramic light-scattering element that includes at least one of a ceramic, a glass ceramic, an immiscible glass, a porous glass, opal glass, amorphous glass, an aerated glass, and a nanostructured glass; and fusion-splicing the glass-ceramic micro-post to the optical fiber by pulling an arc between electrodes across a gap formed by the optical fiber and the glass-ceramic micro-post; maintaining the arc for a time sufficiently long to make facing surfaces of the optical fiber and the micro-post one of malleable and molten; and pushing and thereby fusing together the facing surfaces of the optical fiber and the micro-post. Some embodiments can include fusing the glass-ceramic micro-post to the optical fiber by applying a laser beam to heat up at least one of the facing surfaces of the optical fiber and the glass-ceramic micro-post.
