Chalcogenide Glass Sharpens the Outlook for Infrared Imaging
Chalcogenide glasses — more commonly known as chalcogenides — have been around for some time and offer several benefits over other IR optical materials. They are comparatively lightweight, offer excellent thermal properties, and can be precisely engineered for easy integration with other IR materials. But they have traditionally posed problems for small manufacturers who sought to document consistent production processes for these glasses. In the last ten years, this situation has drastically...
