Infrared Chalcogenide Aspheric Lenses: chalcogenide material has high thermal expansion coefficient, which is an ideal material for non thermal lens. It can perfectly correct and compensate the defocusing of lens caused by temperature change. Due to its thermal imaging ability, it is widely used in industrial temperature measurement lens and thermal imager lens. It will play a great role in the future night vision imaging products.
