About us

Qingyuan Juhang Optical Material Co., Ltd. was established in 2016. It is located in Qingyuan City National Hi-tech Development Zone - Tianan Zhigu. It specializes in research, development and production of chalcogen-based infrared optical materials. The company's core technical team is composed of the world renowned experts in chalcogenide glass materials who has long been engaged in the research and production of infrared optical materials for 20 years. We like to provide high quality infrared optical materials not only in China but worldwide.


















          The company provides high-quality infrared glasses for the thermal imaging core components - chalcogenide glass optical lens. Chalcogenide glass refers to an amorphous material containing one or more of S, Se and Te that are covalently bonded with a certain amount of other metal or non-metal elements such as Ge, As, Sb and so on. Compared with oxide glasses, chalcogenide glasses have much longer infrared cutoff wavelength (>12 μm), and the transmission wavelength can cover three atmospheric windows of 1-3 μm, 3-5 μm and 8-12 μm. Therefore, they are ideal candidate materials for key infrared optical components.
