   •Chalcogenide glasses have unique advantages as infrared lens materials. Chalcogenide glass has high processing efficiency and can be precisely molded. It is 10 times higher than diamond turning, and the cost of raw material is 1/3 of that of germanium single crystal. In the temperature adaptation, the germanium single crystal is“Delicate”, the temperature changes a big, the image is not stable. And chalcogenide glass can be pressure-free ground to minus 40 degrees Celsius to minus 70 degrees Celsius, so 110 degrees of temperature difference.
