INFRARED TRANSMISSION CHALCOGENIDE GLASSES

摘要

A glass composition and a method for producing the glass composition having an improved infrared transmission are provided. The composition includes indium and or cadmium; germanium; phosphorus, arsenic, and/or antimony; silver; lead; and sulfur, selenium, and/or tellurium. The method is performed by melting a mixture for a time period of between about 5 to about 48 hours and mixing the mixture at a temperature range that is between about 600-1000° C.
