Chalcogenide glass Market
Chalcogenide glass has unique advantages as infrared lens material. Chalcogenide glass has high processing efficiency and can be precisely moulded, which is more than 10 times higher than that of diamond turning. The cost of raw materials is 1/3 of that of germanium single crystal. In terms of temperature adaptation, germanium single crystal is more "delicate", with a large temperature change and unstable image. And chalcogenide glass can face the temperature difference of 110 from minus 40 to 70 without pressure.
