Process for producing infrared light transmitting optical fiber |
摘要 |
A process is disclosed for producing an infrared light transmitting optical fiber by drawing a rod of single crystal or polycrystalline metal halide into a fiber through a die; also disclosed is a process for producing an infrared light transmitting optical fiber of step-index type by forming around a single crystal or polycrystalline fiber core, an intimate cladding crystal layer having a lower refractive index than the core by working in the temperature range that does not cause recrystallization of the core or cladding during working.
