    Abstract: A low infrared absorbing lithium glass includes FeO in the range of 0.0005-0.015 wt. %, more preferably 0.001-0.010 wt. %, and a redox ratio in the range of 0.005-0.15, more preferably in the range of 0.005-0.10. The glass can be chemically tempered and used to provide a ballistic viewing cover for night vision goggles or scope. A method is provided to change a glass making process from making a high infrared absorbing lithium glass having FeO in the range of 0.02 to 0.04 wt. % and a redox ratio in the range of 0.2 to 0.4 to the low infrared absorbing lithium glass by adding additional oxidizers to the batch materials. A second method is provided to change a glass making process from making a low infrared absorbing lithium glass to the high infrared absorbing lithium glass by adding additional reducers to the batch material. In one embodiment of the invention the oxidizer is CeO2. An embodiment of the invention covers a glass made according to the method.

    Abstract translation: 低红外吸收锂玻璃包括FeO在0.0005-0.015wt。 ％，更优选0.001-0.010wt。 ％，氧化还原比在0.005〜0.15的范围内，更优选在0.005〜0.10的范围。 玻璃可以进行化学调温，并用于为夜视镜或镜架提供弹道观察罩。 提供了一种改变玻璃制造工艺的方法，该方法是使FeO的高红外吸收锂玻璃的制备范围为0.02-0.04重量％。 ％，并且通过向批料中添加额外的氧化剂，对于低红外吸收锂玻璃的氧化还原比在0.2至0.4的范围内。 提供了第二种方法，通过向批料中添加额外的还原剂来改变玻璃制造过程，从制备低红外吸收锂玻璃到高红外吸收锂玻璃。 在本发明的一个实施方案中，氧化剂是CeO 2。 本发明的实施例覆盖了根据该方法制成的玻璃。
