Abstract: A method for producing long-term bendable glass material includes: bending a glass material in a bending radius in a range of 1 mm to 107 mm; storing the bent glass material for a time period of at least 1 day; inspecting at least a portion of the bent glass material for damage after the storing; and classifying the inspected bent glass material as a reject if damage is detected or as a long-term bendable glass material if no damage is detected.

Abstract: An optical layered composite includes: a substrate having a front face, a back face, a thickness ds between the front face and the back face and a refractive index ns; and a coating applied to the front face. The coating comprises one or more coating layers. For at least one wavelength λg in the range from 390 nm to 700 nm, the coating satisfies one of the following criterion: nc ns, and d c

Abstract: An improved measurement method and a corresponding measurement device are provided that measure the edge strength of plate-shaped elements made of brittle-fracture material. For this purpose, a long sample is drawn apart at the short edges, wherein the force transmission points lie next to the center of gravity of the base surface of the sample.

Abstract: A long-term bendable glass material includes a glass material having a bending radius in a range of 1 mm to 107 mm. The glass material is structured such that a number of breaks developing over a course of time after a storage period of at least one day displays a remaining probability of breaking of less than 0.1 for a storage time period of a maximum of half a year.

Abstract: A method of processing two-dimensional substrates is provided. The method includes placing the substrate onto a substrate carrier and subjecting the substrate to a force acting towards the substrate carrier in an action zone of the substrate, but not in a compensation zone of the substrate. The substrate is predivided while being subjected to the force.
