Description

【発明の詳細な説明】 光学繊維 技術分野 本発明はガラスの芯及びプラスチックのクラツディング（ｃｌ、ａｄｄｉｎｇ　 ）を有する光学繊維に関する。[Detailed description of the invention] optical fiber Technical field The present invention is a glass core and plastic cladding (cl, adding ).

背景技術 既知のそのような繊維において、ガラスはしばしば、低い屈折率を有する石英ガ ラスであり、一方クラッデイングは高減衰珪素ゴムまたは他の高減衰プラスチッ クからなる。石英ガラスの低い屈折率の故に、そのよる。したがって、これらの 繊維は、媒体の長さ、例えば数百メートルの距離にわたって大きな光カ乞伝達さ せるためには適当でない。Background technology In known such fibers, the glass is often a quartz glass with a low refractive index. cladding is made of high-damping silicone rubber or other high-damping plastic. Consists of ku. This is due to the low refractive index of quartz glass. Therefore, these Fibers transmit large amounts of light over distances of medium length, e.g. hundreds of meters. It's not appropriate to do so.

そのような繊維の助けを用いて高い光力を伝達する方法はそれらの直径を増大す ることである。しがしな−から、これはより多（の費用のがかろ繊維を生ずる一 万、それらは同時により柔軟性が小さいであろう。The method of transmitting high optical power with the help of such fibers is to increase their diameter. Is Rukoto. Since it is more durable, this results in more expensive fibers. However, they would also be less flexible.

本発明の開示 本発明の目的は高い数値のアバ−チアを有する光学繊維乞提供することであり、 その繊維はしたがって媒体の長さの距離にわたって高い光力乞伝達するために適 当で゛ある。Disclosure of the invention An object of the present invention is to provide an optical fiber having a high numerical aperture, Its fibers are therefore suitable for transmitting high optical powers over medium length distances. That's true.

これは特許請求の範囲に開示された特徴点が与えられる本発明に従う繊維により 提供される。This is achieved by the fiber according to the invention which is provided with the features disclosed in the claims. provided.

本発明実施のための最良の態様 本発明による光学繊維はガラスの芯及びプラスチックのクラツディングを含む。BEST MODE FOR CARRYING OUT THE INVENTION Optical fibers according to the invention include a glass core and plastic cladding.

本発明によれば、ガラスは屈折率を増大する酸化物類を有する硼珪酸ナトリウム ガラスであり、一方プラスチックは低い屈折ｔ＝ｗ有少な（とも１．５２の屈折 率乞ガラスに与えることが意図される屈折率を増大する酸化物ばＰｂＯ１Ｂａ○ 、Ｃａｂ、ＭｇＯ、Ｚ　ｒ　Ｏ２及びＺｎＯの組み合せを含み、一方、多くとも １．４２の屈折率乞有丁べき光学的圧低い減衰のプラスチックは１例えば会社シ ンエソ（５ＨＩＩ、ＩＥＴＳＵ　）により供給されそして２５°Ｃで１．４１の 屈折率乞有するタイプの光学的に純粋な珪素ゴムを含む。According to the invention, the glass is made of sodium borosilicate with oxides that increase the refractive index. glass, while plastic has a low refraction t=w (both have a refraction of 1.52). The oxide that increases the refractive index that is intended to be imparted to the glass is PbO1Ba○ , Cab, MgO, ZrO2 and ZnO, while at most A low attenuation plastic with a refractive index of 1.42 should have an optical pressure of 1, for example a company brand. 5HII, IETSU) and 1.41 at 25°C. Contains a type of optically pure silicone rubber with a high refractive index.

重量パーセントにより表わされた次の組成ぞ有する第１ガラス芯が製造される： Ｚｎ０　３−１ このガラス芯の屈折率は１．５２であった。上記に従うプラスチックのさやを用 いて、その繊維は０．５７の数値のアバ−チアが与えられた。A first glass core is produced having the following composition expressed in weight percent: Zn0 3-1 The refractive index of this glass core was 1.52. Use plastic pods as per above. The fiber was given a numerical value of 0.57.

また重量パーセントで表わされた次の組成を有する第２ガラス芯が製造された： ８１０２５１．４ Ｎａ２０　１８．に のガラス芯の屈折率は１．５５に達した。上記に従うプラスチックのクラツディ ング２用いて、この他の繊維は０．６４の数値のアバ−チアが与えられた。A second glass core was also produced having the following composition expressed in weight percent: 810251.4 Na20 18. to The refractive index of the glass core reached 1.55. Plastic kratzdi according to the above This other fiber was given an abbrity value of 0.64 using Rating 2.

珪素ゴムクラツディングの厚さは１０と５０との間のマイクロメータで選ばれる ことが好ましい。The thickness of the silicone rubber cladding is selected in micrometers between 10 and 50. It is preferable.

タラノデイング乞保護するために、これは例えば、エポキシアクリレートの保護 被覆乞用いて被覆される。To protect the talanoding, this is e.g. epoxy acrylate protection Covered with a coating.
