<p>A reflecting mirror (10) comprising a standard casing or enclosure (12) and a sheet of an alkali metal-zinc-borosilicate glass member (16) bonded to a reflecting surface (14), 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.</p> |
