Abstract
PURPOSE:To obtain a fiber for infrared light with high endurance and operational performance by forming a resin coat on the outside of a fibrous infrared light transmitting path of metal halides and coating the outside of the resin coat with a metal by vacuum deposition, sputtering, ion plating or other method. CONSTITUTION:An extrusion billet composed of core part 1 and clad part 2 made of NaCl and KCl, KCl and KBr, CsI and CsBr, AgCl and AgBr or KRS5 and 6, respectively is put in extrusion vessel 11, heated with heating furnace 14, and pressurized by extrusion punch 13 in the direction of dies 12 to obtain a fibrous light transmitting path. Coat 3 of tetrafluororesin, silicone resin, epoxy resin or the like is then formed on the outside of the path, and coat 3 is coated 4 with Fe, Ni, Cr, Al or their alloy by vacuum deposition, sputtering or other method to obtain a fiber for infrared light with high endurance and operational performance.
