Oxyhalogenated glasses transmitting in the infrared and process for their preparation

摘要

Oxyhalogenated glasses transparent in the infrared up to approximately 6500 nm. The glasses of the invention consist essentially of antimony, oxygen and at least one halide of an element belonging to groups Ia, IIa, IIIa, IVa, IIb and VIIb of the Periodic Classification of the elements. Use of these glasses in the production of optical components and of optical waveguides. <IMAGE>
