PURPOSE:To obtain readily bundle fibers of high performance, by bundling fluoride glass fibers and chalcogenide glass fibers both having a fluororesin as a clad, inserting the resultant bundled fibers into a tube of the same material, and drawing a wire while heating. CONSTITUTION:A glass rod 1 consisting of a fluoride glass as a core material is inserted into a fluororesin tube 2 to be a clad, contained in a vacuum vessel 4 connected to a vacuum pump 3, and drawn into a wire while heating to prepare a fluoride glass fiber (FGF). On the other hand, a fluororesin tube 2 containing a chalcogenide glass rod inserted therein is drawn into a wire while heating to prepare a chalcogenide glass fiber (CGF). One - several fibers (FGF) and (CGF) are bundled and inserted into a fluororesin tube 7, which is reheated and drawn into wires to give the titled bundle fibers. Thus, these fibers can be drawn while heating to produce readily the bundle fibers.

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing a bundle fiber that can simultaneously transmit visible light and infrared light.

(Prior Art) Conventionally, visible light has been used as a bundle fiber (hereinafter simply referred to as bundle fiber) that can simultaneously transmit visible light (approximately 0.4 μm to approximately 0.8 μm) and infrared light (0.8 μm or more). There are fibers that have a mixed arrangement of visible fibers that pass only light and infrared fibers that pass only infrared light (for example, JP-A-58-
(See Publication No. 93008).

(Problems to be Solved by the Invention) However, since the above-mentioned device simply bundles an appropriate number of visible fibers and infrared fibers, it is difficult to manufacture a high-quality product. Furthermore, it has been difficult to obtain bundle fibers with excellent strength.

Although not shown in detail in the above publication, conventional visible fibers and infrared fibers each use quartz glass or chalcogenide glass as their core, and tetrafluoroethylene-hexafluoropropylene copolymer resin ( (hereinafter referred to as FEP) and tetrafluoroethylene resin (hereinafter referred to as FEP)
Since a fluororesin such as TFE (hereinafter referred to as TFE) was used, there were the following problems. That is, the softening temperature of quartz glass is extremely high at about 1500 to 2000'C, whereas that of chalcogenide glass and the above-mentioned fluororesin is about 3.
Since the temperature is relatively low at 00'C, it is difficult to draw the wire at the same time.

In addition, the transmission wavelength range of quartz glass is approximately 0.4μ ~ 1.8μ
If a visible fiber made of quartz glass and an infrared fiber made of chalcogenide glass are combined into a bundle fiber, light in the wavelength range of 1.8 μm or more will be transmitted only through the chalcogenide glass fiber. Therefore, such a bundle fiber is disadvantageous because the transmission efficiency of infrared light becomes poor.

(Means for Solving the Problems) In order to achieve the above object, in the present invention, a fluororesin tube with a fluoride glass rod inserted therein is heated and drawn to produce a fluoride glass fiber,
On the other hand, a chalcogenide glass fiber was produced by heating and drawing a fluororesin tube into which a chalcogenide glass rod was inserted, and the fluororesin tube into which one or more of the fluoride glass fibers and chalcogenide glass fibers were bundled and inserted was drawn again. The wire is drawn under heating.

(Example) Hereinafter, a method for manufacturing a bundle fiber according to the present invention will be explained based on the drawings. Since fluoride glass fibers and chalcogenide glass fibers differ only in their core materials, the method for manufacturing fluoride glass fibers will be described below first.

First, as shown in FIG. 1, a glass rod 1 made of fluoride glass (e.g. glass mainly composed of BaFl -GdF, -ZrF4 and added with AI!F) is used as a core material, and this is made of FEP or TFE. A fluororesin tube (hereinafter referred to as resin tube) 2 is inserted into a vacuum vessel 4 to which a vacuum pump 3 and the like are connected.

Then, the vacuum container 4 is heated by the heater 5 (temperature of about 100 to 200°C), and the resin tube 2 into which the glass rod 1 is inserted is heat-shrinked in a vacuum, so that the outer circumferential surface of the glass rod 1 is A preform P covered with the resin tube 2 as a cladding is produced.

Then, if necessary, for example, when the glass rod 1 has a relatively large diameter or when it is desired to obtain a core with an extremely small diameter,
As shown in FIG. 3, the preform P is heated and drawn, and as shown in Figure 41, a relatively small-diameter fluoride film with fluoride glass as the core IF and a resin tube as the cladding 2F. Glass fiber FGF is manufactured. Note that 6 is a heater.

In the above, the softening temperature of both the core made of fluoride glass and the cladding made of resin tube is 300'C.
Since the front and back are similar, drawing can be done extremely smoothly and with simple temperature control.

In addition, in order to manufacture the chalcogenide glass fiber CGF, a corcogenide glass (for example, As-5 glass, As-Ge-8e glass) is used as the glass rod 1, and the same procedure as for the above-mentioned fluoride glass fiber FGF is performed. As shown in FIG. 4(B), chalcogenide glass fiber CG has chalcogenide glass as the core IC and resin tube as the cladding 2F.
F is obtained. In this case, since the softening temperatures of the core made of chalcogenide glass and the cladding made of resin tube are similar, around 300'C, the line can be drawn smoothly and with simple temperature control as in the case described above.

In this way, the fluoride glass fiber FGF,
Chalcogenide glass fiber CGF can be obtained, but the permissible transmission wavelength range of the former is approximately 0.6 μfi to 4 μm.
, the latter one is about 1 μfi ~ 9 μ chiku, and 1 μ? FL
Since the wavelength ranges of ~4μ milk overlap, infrared light can be efficiently transmitted. The fluoride glass fiber FGF can transmit not only visible light but also infrared light.

Next, a procedure for manufacturing a bundle fiber BF using the fluoride glass fiber FGF and the chalcogenide glass fiber CGF formed as described above will be described.

First, as shown in FIG. 7 to a temperature of 100 to 20 G'C), and as a result of the thermal contraction of the resin tube 7, as shown in FIG.
A bundle preform BP is produced by bundling an appropriate number of fluoride glass fibers FGF and chalcogenide glass fibers CGF.

Next, as shown in FIG. 7, while heating the bundle preform BP with the heater 9, the bundle preform BP is drawn from one end thereof. In this case, since the cladding of the fluoride glass fiber FGF and the chalcogenide glass fiber CGF are both made of the resin tube 2 made of the same material as the resin tube 7, the resin tube 2 fuses with the resin tube 7 during drawing, as shown in FIG. Thus, a bundle fiber BF is manufactured in which one or more fluoride glass IFs and chalcogenide glass ICs are mixed together as cores in the cladding a.

(Effects of the Invention) According to the method of the present invention, a fluorite glass rod and a chalcogenide glass rod having approximately the same softening temperature are used as cores, and a resin tube having approximately the same softening temperature as these glass rods is used as the core. Since these fibers are made into cladding, it is possible to heat and draw these fibers at the same time, so that a bundle fiber can be easily manufactured.

Moreover, the permissible wavelength range for transmission of fluoride glass is approximately 0.
The bundle obtained by the method of the present invention has a diameter of 6 μm to 4 μm and can transmit not only visible light but also infrared light, and the permissible wavelength range for transmission of chalcogenide glass is approximately 1 μm to 9 μm. Fibers can transmit light of any wavelength in the range from visible light to infrared light.
The performance of this type of bundle fiber can be greatly improved, such as being able to be used for spectroscopic measurements that measure absorption characteristics over a wide range from the visible light region to the infrared light region.
