Thin sheet mirror and Nd2O3 doped glass

摘要

A reflecting mirror comprising a sheet of an alkali metal-zinc-borosilicate glass bonded to a reflecting surface, the glass sheet having a thickness less than 0.5 mm, and being doped with Nd₂O₃ in an amount sufficient to substantially reduce the spectral transmission of the glass in the wavelength range of 565-595 nm, and further doped with CO₃O₄ in the amount of 10-100 ppm, preferably 20-80 ppm, more preferably 30-60 ppm to reduce the pink hue of the glass.
