SHEET GLASS AND PHOTOELECTRIC CONVERTER-USE SHEET GLASS

摘要

Sheet glass for delivering a high transmittance intrinsically possessed due to its composition even though formed on molten tin. The sheet glass has the difference in visible light reflectance of up to 0.25% between at a surface formed in contact with molten tin and at a surface on the opposite side, has, when it is 4 mm thick, a light transmittance of at least 91.5% at a wavelength of 540 nm and at least 91.0% at a wavelength of 450 nm, and has, after a ultraviolet ray specified in JIS R3212 light-fastening test is applied for six hours, a light transmittance of at least 91.0% at a wavelength of 540 nm and at least 90.5% at a wavelength of 450 nm.
