Abstract: A light control film is described comprising alternating transmissive regions and absorptive regions disposed between the light input surface and the light output surface. The absorptive regions have an aspect ratio of at least 30. In some embodiments, an absorptive layer or reflective layer is disposed between the alternating transmissive regions and absorptive regions and the light input surface and/or light output surface. In another embodiment, the alternating transmissive regions comprise an absorptive material. The light control film can exhibit low transmission of visible light and high transmission of near infrared light. Also described is a light detection system comprising such light control films and a microstructured film.

Abstract: Methods of forming an array of patterns on a substrate are provided. An array of protective tiles formed from a protectant resin is provided to cover an array of sub-regions on the substrate. An array of patterns is formed on the substrate by sequentially repeating steps (i) and (ii) for each sub-region: (i) removing the protective tile from one of the sub-regions to expose the first major surface underneath; and (ii) forming a pattern on the exposed first major surface within the one of the sub-regions.

Abstract: An optical system includes an optical film curved about a first axis and a light control film curved about the first axis. The light control film can be disposed between a light source and the optical film. The optical film includes a microstructured first major surface and an opposing second major surface. The microstructured first major surface defines a linear Fresnel lens including a plurality of Fresnel elements extending longitudinally along the first axis. The first major surface of the optical film faces the light control film. The light control film can include a plurality of alternating optically transmissive and optically absorptive regions extending longitudinally along the first axis such that in a cross-section orthogonal to the first axis, for at least a majority of the optically transmissive regions, a centerline between adjacent optically absorptive regions is substantially normal to a major surface of the light control film.

Abstract: The present disclosure provides fluidic devices. A fluidic device includes a) a first bondable polymeric layer having a first major surface that is substantially planar; b) a second polymeric layer having a first major surface that is substantially planar; and c) a hydrophilic mask material disposed on a first portion of the first major surface of the first bondable polymeric layer. A surface of the hydrophilic mask material exhibits an advancing contact angle with water of less than 90 degrees. A second portion of the first major surface of the first bondable polymeric layer is bonded to a first portion of the first major surface of the second polymeric layer. The hydrophilic mask material and a second portion of the first major surface of the second polymeric layer are in direct contact with each other at at least one point. An open volume is defined by interstitial space located between the hydrophilic mask material and the second portion of the first major surface of the second polymeric layer. The open volume comprises two or more openings and at least one of the openings is located at an edge of the first bondable polymeric layer. The fluidic devices can be formed to have small volumes for use as precision fluidic devices, such as blood glucose testing strips.

Abstract: Methods of making metal patterns on flexible substrates are provided. A releasable solid layer is selectively formed on a patterned surface of the flexible substrate by applying a liquid solution thereon. The releasable solid layer is transferred from the patterned surface to a transfer layer where the metal patterns are formed.

Abstract: An optical film includes a structured film and a light control film formed on the structured film. The structured film includes a substrate and a plurality of polymeric microstructures formed on a major surface of the substrate. Each microstructure includes an optical facet and a sidewall meeting the optical facet at a ridge of the microstructure. The light control film includes an optically transparent material disposed on and covering the plurality of polymeric microstructures, and a plurality of optically absorptive louvers formed in the optically transparent material opposite the structured film. The louvers extend along a longitudinal direction and are spaced apart along an orthogonal transverse direction. The louvers have an average depth D into the optically transparent material and have an average width W in the transverse direction. D/W can be greater than 2. The optical film is integrally formed.
