    Abstract: A system includes a stage, a detector and a measuring device. The stage is configured to hold a substrate. The substrate includes a plurality of tapered structures, and each of the plurality of tapered structures includes a tapered wall between first and second openings at opposite ends of the plurality of tapered structures. The detector is tilted at a first angle and configured to measure light reflected from the tapered wall at about 90 degrees to the tapered wall. The first angle depends at least in part a second angle between the tapered wall and a longitudinal axis running through the tapered structure. The measuring device is configured to determine a characteristic of the tapered wall and whether the characteristic of the tapered wall is above or below a threshold.

    CPC classification number: G02B1/115

    Abstract: A screen protector is described herein that is configured to be releasably attached to an optical coating on a glass-containing display of an electronic device. The protector comprises: a glass-containing substrate comprising an outer and inner primary surface; an antireflective (AR) coating on the outer primary surface; and an interlayer on the inner primary surface for releasable attachment to the optical coating on the display. The interlayer comprises an adhesive, a physical thickness from about 10 μm to 500 μm, and one or more refractive indices from ˜1.2 to 1.6. Further, an average photopic reflectance of the screen protector can be less than 2% for all incident angles from 0° to 30°. The interlayer can comprise optically clear adhesive (OCA), polymer-containing layer, and releasable adhesive layers. An anti-splinter (AS) film can be between the interlayer and the substrate. The interlayer and/or AS film may be a cyclo olefin, cellulose triacetate or polyurethane.

    Abstract: Transparent or translucent sound diffuser-absorbers include a first glass sheet of less than 0.8 mm thickness and a second glass sheet of less than 0.8 mm thickness with a transparent or translucent adhesive layer there between, the adhesive layer adhering the first and second sheets in a fixed configuration such that a first major surface of the first glass sheet has a smooth, repeatedly rising and falling shape. The diffuser-absorbers further include a plurality of through-holes extending through the first glass sheet and through the adhesive layer and through the second glass sheet. Methods of forming are also disclosed.

    Abstract: Embodiments of durable, anti-reflective articles are described. In one or more embodiments, the article includes a substrate and an anti-reflective coating disposed on the major surface. The article exhibits an average light transmittance of about 94% or greater over an optical wavelength regime and/or an average light reflectance of about 2% or less over the optical wavelength regime, as measured from an anti-reflective surface. In some embodiments, the article exhibits a maximum hardness of about 8 GPa or greater as measured by a Berkovich Indenter Hardness Test along an indentation depth of about 50 nm or greater and a b* value, in reflectance, in the range from about −5 to about 1 as measured on the anti-reflective surface only at all incidence illumination angles in the range from about 0 degrees to about 60 degrees under an International Commission on Illumination illuminant.
