Chalcogenide lens elements and methods of manufacturing such lens elements are provided. In one example, a method includes depositing a first chalcogenide layer on a substrate. The method further includes applying a first stamp to the first chalcogenide layer. The method further includes reflowing, in response to applying the first stamp, the first chalcogenide layer to form a first shaped chalcogenide layer. The method may further include singulating the substrate and the first shaped chalcogenide layer to obtain a plurality of chalcogenide lens elements.

Chamfering processing for chamfering an edge face of a disk-shaped glass plate includes a step of disposing the glass plate such that a portion of the glass plate is disposed in a heating space for heating the glass plate and the remaining portion is disposed outside the heating space; and a step of softening a portion of the edge face of the glass plate by irradiating a circumferential portion of the edge face with a laser beam outside the heating space while rotating the glass plate in one direction around the center of the glass plate, and heating the softened portion of the edge face that has reached the heating space through the rotation.

A display device with a display element having a display surface and a cover glass sheet, having a first textured surface, such that the first textured surface is facing the display element. The first textured surface has a surface roughness defined by a first arithmetic amplitude value, Ra1, being equal to or greater than 0.12 μm (Ra1≥0.12 μm) and a first spacing value, Rsm1, being equal to or greater than 45 μm (Rsm1≥45 μm) both measured on an evaluation length of 12 mm and with a Gaussian filter of which the cut-off wavelength is 0.8 mm. The first textured surface is in direct contact with the display surface over at least a portion of a contact area of the first textured surface.

The present disclosure relates to a method of manufacturing a curved laminated glass and the curved laminated glass. The method comprises preparing a curved soda lime glass, providing a functional layer on one surface of an alkali-free glass, disposing a lamination film or a bonding agent between the curved soda lime glass and the functional layer, and elastically deforming the alkali-free glass, and laminating the alkali-free glass with the curved soda lime glass.

The present disclosure relates to an apparatus for cutting substrate material, the apparatus including: a mounting frame; a base mounted to the mounting frame; an upper cutter device disposed on the mounting frame; and a substrate material clamp disposed on the upper cutter device and used to clamp substrate material, the substrate material clamp including a clamp body and a flattening member connected to the clamp body, and the flattening member being used to flatten the substrate material. In the above technical solution, the flattening member is provided on the lower surface of the substrate material clamp, and during the process that the substrate material clamp approaches the base, the flattening member flattens the curled substrate material, and thus the quality of the substrate material is improved.

A method is provided for producing a patterned glass wafer for packaging electronic devices in a wafer assembly. The method includes placing a glass sheet between two mold halves and heating until the glass sheet softens, while the mold halves are pressed against one another so that the glass sheet is reshaped and forms a patterned glass wafer. The first mold half has an array of projections and the second mold half has an array of recesses. The mold halves are arranged and shaped so that the recesses and projections oppose each other. The projections introduce cavities into the glass sheet during the reshaping and with the glass flowing into the recesses of the second mold half during the reshaping. The recesses are deep enough for the glass to at least partially not come in contact therewith and to form a convexly shaped glass surface in each recess.
