However, with the effects on permeability by the impurity which is brought by raw material or melting process, the producing of high-performance infrared chalcogenide glass materials is limited by the technologcial conditions to a large extent. First of this paper introduces some relevant knowledge and research significance, including the fundamental knowledge about the origin and development of chalcogenide glass and Te-based chalcogenide glass. And then introduces some theory basis including optical loss on chalcogenide glass, the effects on chalcogenide glass by oxygen impurities and the method of eliminating oxygen. Then introduces the producing of Ge-Se-Te chalcogenide glass samples and some performance tests about mechanical, physical and related optical properties. The related calculation and analysis of glass samples and test data are introduced in later. At last, this paper gives its conclusion. 【KEYWORDS】Chalcogenide glass；deoxidant；Optical properties。 目　录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc293508592 摘　要 PAGEREF _Toc293508592 \h II HYPERLINK \l _Toc293508593 Abstract PAGEREF _Toc293508593 \h III HYPERLINK \l _Toc293508594 目　录 PAGEREF _Toc293508594 \h IV HYPERLINK \l _Toc293508595 引言 PAGEREF _Toc293508595 \h 1 HYPERLINK \l _Toc293508596 1 绪论 PAGEREF _Toc293508596 \h 3 HYPERLINK \l _To
