Thin sheet mirror and Nd2O3 doped glass
First Claim
1. A reflecting mirror comprising a sheet of an alkali metal-zinc-borosilciate glass bonded to a reflecting surface, the glass sheet having a thickness less than 0.5 mm, and being doped with Nd2O3 to substantially reduce the spectral transmission of the glass in the wavelength range of 565-595 nm, wherein the alkali metal-zinc-borosilicate glass consists essentially, by weight percent on an oxide basis, of
SiO255-70%
Al2O30.5-4.5%
B2O36-14%ZnO3-10%Na2O5-11%K2O2-9%
Na2O + K2O7-20%Nd2O35-10%.

Abstract
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.
