GLASS FOR MAKING GRADIENT TRANSLATOR OF IMAGE BY METHOD OF IONIC EXCHANGE

摘要

FIELD: glass industry. SUBSTANCE: glass has the following composition, mole%: $$$, 56-63; $$$, 10-13; $$$, 10-12; $$$, 8-11; $$$, 0.1-0.5; $$$, 2-5, where $$$ - Mg, Ca, Zn, Ba, Sr, Pb; $$$, 0.5-3 where $$$ - La, Ge, Ti, Ta, Nb, W. Coefficient of glass refraction is 1.58-1.61, maximal gradient of refraction index is (-130)-(-160) x $$$. Gradient translators were made by method of ionic exchange in salts melt. EFFECT: enhanced quality of glass. 2 tbl
