Chalcogenide Glass IR Blank

Chalcogenide optical glass blanks are crafted from a unique blend of chalcogen elements such as sulfur, selenium, and tellurium. These glass lens blanks are essential for manufacturing advanced optical components that operate efficiently within the infrared spectrum. They are widely used in thermal imaging, security systems, and optical communication devices due to their excellent IR transmission properties.
