Abstract: A glass substrate comprises: a first surface with surface features having an average width, an average height, a ratio of the average height to the average width of from about 0.04 to about 0.24, and the first surface has a haze value of 3% to 40%. The glass substrate can be transparent to electromagnetic radiation in the visible spectrum. The glass substrate can have a composition of: 61-75 mol. % SiO2; 7-15 mol. % Al2O3; 0-12 mol. % B2O3; 9-21 mol. % Na2O; 0-4 mol. % K2O; 0-7 mol. % MgO; and 0-3 mol. % CaO. The first surface can have an average surface roughness Ra of from 10 nm to 1,000 nm. The first surface can have an average characteristic largest feature size of from 200 nm to 50 ?m. The ratio of the average height to the average width can be from 0.06 to about 0.08.

Abstract: An article that includes: a glass-based substrate comprising a thickness, a primary surface and a compressive stress region that extends from the primary surface to a selected depth; and a textured region defined by the primary surface. The textured region comprises a surface roughness (Ra) of at least 10 nm. The article can also comprise a Knoop Scratch Threshold of at least 9 Newtons (N).

Abstract: A glass sheet is formed on a mold into a glass article having a three-dimensional shape. The mold, with the glass article thereon, is arranged within an interior space of a radiation shield such that the mold is between a leading end barrier and a trailing end barrier of the radiation shield. The mold, glass article, and radiation shield are translated through a sequence of cooling stations while maintaining the mold between the leading and trailing end barriers, wherein the leading and trailing end barriers inhibit radiation heat transfer at leading and trailing ends of the mold.

Abstract: A lens array block comprises a plurality of lens barrels joined to one another form a three-dimensional unitary structure. Each lens barrel comprises a stepped cylindrical chamber having a through hole with an internal profile having first and second steps that are spaced apart through the height of the through hole, the second step being radially inward of the first step. An image capturing unit comprising the lens block array, and methods of fabrication and assembly are also described.
