Method for Processing Surface of Light-Transmitting Glass and Light-Transmitting Glass Processed by said Method

摘要

To impart antiglare properties without reducing the amount of transmitted light, a method for processing a surface of light-transmitting-glass according to the present invention comprises a blasting step of ejecting abrasive grains with particle sizes of #800 to #3000 (average particle diameter 14 μm to 4 μm) such as WA (white alundum: high-purity alumina) having higher hardness than that of the glass onto a light-receiving surface of the glass having light-transmitting property to be processed for forming indentations and protrusions in the light-receiving surface of the glass, and after the blasting step, a hydrofluoric acid treatment step of immersing the light-receiving surface of the glass into a hydrofluoric acid solution in 10% to 20% concentration for 30 to 600 seconds thereby increase a height (amplitude) of indentations and protrusions of the surface of light-transmitting-glass.
