Method for producing an optical fiber of halide glass, particularly an infrared permeable fiber of heavy metal fluoride glass

摘要

A method for manufacturing optical fibers from halide glass is provided. The method includes the steps of drawing a glass mass into a fiber in a dry gas atmosphere which contains a drying agent. In a further step of the process, an OH band which may still be present can be reduced by treating the fiber with a gaseous drying agent.
