バーの透過性が悪いという欠点があった。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an infrared fiber having a core made of a metal halide compound and a method for manufacturing the same. Conventional infrared fibers of this type (infrared fibers whose core is made of a metal halide compound) use AgC1 for the cladding, but because AgCf itself is soft, its mechanical strength and durability are insufficient. And, one of the manufacturing methods is bamboo-like AgC1! A rod-shaped metal halide compound is inserted inside the aluminum pipe and pulled out to perform the wire drawing process.In this method, the core and cladding parts are deformed by uniform stress. Since it is difficult and difficult to add the above-mentioned infrared rays, the interface becomes uneven, resulting in the disadvantage that the produced infrared breaker has poor transmittance.

ァイバ及びその製造方法を提供することを目的とする。In view of these conventional drawbacks, the present invention provides an infrared fiber having a core made of a metal halide compound, which has excellent mechanical strength, durability, and transparency, and is easy to manufacture. The purpose is to provide a method.

Next, 7 is a container for softening, 8 is a heater for heating, and 9 is a cover for atmosphere adjustment, and a chalcogenide compound 11 (described later) that is introduced into the container 7 from an input port 10 is heated by the heater 8. It softens and becomes syrup-like, coats the outer periphery of the core part 6 which is being extruded, and is then cooled to form a clad part 12, thereby producing a step index type infrared fiber 5. At this time, the atmosphere during molding of the infrared fiber 5 is adjusted by Ar gas introduced from the inlet 13 and discharged from the outlet 14. Numeral 15 is an air vent, and 16 is a plug.

The figure shows another embodiment of the invention. In this embodiment, an elongated core part 6 made of a metal halide compound, manufactured in advance by extrusion molding, is wound up on a winding bobbin 17, and then the core part 6 is sequentially rolled out in the direction of the arrow. The step index type infrared fiber 5 is manufactured by heating the chalcogenide compound (described above) 11, which has been softened and becomes starch syrup-like by being heated by the heater 18, and then cooling it.

する。In addition, 19 in the figure is a heating crucible. Alternatively, an infrared fiber may be manufactured by depositing a chalcogenide compound on the outer periphery of a pre-formed core using a vapor deposition method. In any of the three manufacturing methods described above, unlike the conventional method described at the beginning, the interface between the core part and the cladding part does not become uneven, and therefore the transmittance of the infrared fiber is improved.

This can be easily carried out by taking advantage of the characteristics of the compound, which are that it is easy to soften and that it is easy to vapor deposit.
