    摘要: A glass or glass-ceramic plate is provided that has two side faces, a thickness of between 2 mm and 6 mm, a circumferential edge face, a flatness less than or equal to 0.1%, and a region of a first face having a mean surface roughness of less than 0.5 μm and a standard deviation of the surface roughness of less than 0.1 μm. The mean surface roughness and the standard deviation are determined by measuring a roughness at nine points on the first face by measuring a line profile with a stylus device and with evaluation according to ISO 4827. The nine points are at least 5 cm apart from one another. The plate further includes a coating on two subregions of the region that are at least 3 cm apart from one another, where the coating has a raggedness in the subregions that differ by not more than 10%.

    摘要: A method for preparing optical fibers formed with high-particle-coated porous polymeric outer coating layer is provided. The method includes preparing a coating suspension solution by dispersing a plurality of particles into an organic solvent system, immersing one or more optical fibers into the coating suspension solution, removing the one or more optical fibers from the coating suspension solution to form high-particle-coated porous polymeric outer coating layer after drying. Concentrations and compositions of the particles in the coating suspension solution, concentrations and compositions of the organic solvent system, the period of time of immersing, or the external environment are adjusted such that the optical fibers is formed with high-particle-coated polymeric outer coating layers having desirable coating masses, coating thicknesses, or coating morphologies.
