Websurface wettability properties of commercial soda-lime-silica float glass subjected to various surface preparation methods. The comparative evaluation of vacuum evaporated chromium thin film adhesion strength to float glass treated under different surface preparation methods was performed using scratch tests. Also, the influence of float glass Surface quality, or surface roughness, refers to how much an optical glass surface deviates from an ideal. Poor surface quality can cause unwanted light scattering in applications that require particular system wavelengths. Scratch-dig specifications—defined as the presence of scratches, bubbles, or … See more Surface flatness is the measure of how flat a surface is; this test is critical for glass productssuch as windows, mirrors, and plano-lens. The surface flatness test accounts for surface … See more This specification applies to curved optical surfaces — surfaces with power — and is tested similarly to flatness; the curved surface is stacked against a reference surface, a highly calibrated reference gauge. The air gaps … See more During polishing processes, there’s always a risk of small irregularities occurring on the surface of the glass. Surface finish testing, or surface … See more The irregularity specification is used to describe the deviation of a test surface’s shape from the shape of its corresponding reference surface. … See more exterior use wire
