Among these elements which contaminate the optical glass quality, the most frequently met are the transition metals, the rare earths, the oxides, the carbon traces and some ions (NH.., Cl....) resulting from NH.HF. or CCl. treatment. The effects of such impurities on the glass pr

Some of the lower Tg glasses, however, did exhibit detectable structural relaxation on annealing at temperatures as low as 100°C over roughly a one year time perio
