Method of manufacturing an infrared optical fiber

摘要

A method of manufacturing an unclad infrared optical fiber hot extrudes silver halide crystals through a die while simultaneously applying a pressure of 5 to 15 tons/cm2 to the crystals and a tensile load to the forming fiber, the tensile load being greater than the yield stress but smaller than the rupture stress of the infrared optical fiber. The method provides an infrared fiber having minimal variation in linearity.
