<title>Production of infrared-transmitting chalcogenide glasses</title>

Abstract

Chalcogenide glasses have been produced commercially for use in infrared systems for almost 50 years. Only three glass compositions in the western world have been produced and used in ton quantities: As₂S₃, Ge₃₃As₁₂Se₅₅, and Ge₂₈Sb₁₂Se₆₀. Production of these three compositions at Amorphous Materials will be discussed. Physical properties of the glasses will be compared and related to the properties of other IR optical materials. Drawing of chalcogenide glass fibers at Amorphous Materials will be described.
