この発明は顕微鏡を用いるMjII着接続機における光
ファイバの観察方法に閥し、特に光ファイバを上から直
接見忘直接像とミラーを使って側面から見た反射像とを
同時に観察する方法に関するものである。[Detailed Description of the Invention] This invention relates to a method of observing an optical fiber in an MjII splicing machine using a microscope, and in particular, it is divided into a method for observing an optical fiber in an MjII splicer using a microscope, and in particular a method for observing an optical fiber directly from above, a direct image, and a reflected image seen from the side using a mirror. This relates to a method for simultaneously observing.
発明のf景と目的 従来の観察方法の概略を1第7図」に示ず。Vision and purpose of invention An outline of the conventional observation method is shown in Figure 1.
10は光ファイバ、11は顕微ムz112は対物レンズ
、14はミラー、16は電極俸である。10 is an optical fiber, 11 is a microscope, 112 is an objective lens, 14 is a mirror, and 16 is an electrode.
顕微鏡11によって、光ファイバ10を上から直桜見た
直接像10aと(第2図)、ミラー14を使って光ファ
イバ10を側方から見た反射像10bとが同時に観察さ
れる。Using the microscope 11, a direct image 10a of the optical fiber 10 viewed directly from above (FIG. 2) and a reflected image 10b of the optical fiber 10 viewed from the side using the mirror 14 are observed simultaneously.
ところがこの場合光ファイバ10から対物レンズ12ま
での光のみちすじの長さは、直接像IDaの場合はAB
であるのに対して、反射像10bの場合はAODであっ
て、こぢらの方がAOだけ長い。However, in this case, the length of the light path from the optical fiber 10 to the objective lens 12 is AB in the case of the direct image IDa.
On the other hand, the reflected image 10b is AOD, and is longer by AO.
一般に対物レンズ12には倍率がIO倍程度のものを使
っているので焦点深変は約10=μmくらいである。そ
れに対してACの長さは0,5〜Q、jf關くらいにし
であるので、直接イ后、10aと反射像10bのピント
が同時に合わない。そのためにピント合わゼのやり1η
しが必要である。Generally, the objective lens 12 used has a magnification of about 10 times, so the change in depth of focus is about 10 μm. On the other hand, since the length of AC is about 0.5 to Q, jf, the direct image 10a and the reflected image 10b cannot be brought into focus at the same time. For that reason, I have to focus 1η
It is necessary to
このつ自明の目的は、ピント合わせ+M、L、を行なわ
す1こ、1回のピント合4っせによって直接像10aと
反射1ぶ10t+の両方を同時に観察できるようにする
ことにある。The obvious purpose of this is to make it possible to observe both the direct image 10a and the reflected image 10t+ at the same time by performing focusing +M, L and one focusing.

「第3図」のように、
光ファイバ10からミラー14を経て対物レンズ12に

および反射像1[1bのピント合わせを行なう上におい
て、AODの光のみちすじの長さとABの光のみちすじ
の長さと力く実質的に等しくなったと同じように作用す
るようにすること、を特徴とする。As shown in Figure 3 of Wrinkle Clear (II 7), there is a path at the end of the AOD from the optical fiber 10 to the objective lens 12 via the mirror 14, where the refractive index is greater than that of air and the light of the AOD is By inserting the transparent medium 20 having a predetermined length along the path, the straight Wm10a
and in focusing the reflected image 1 [1b, the length of the path of the AOD light and the length of the path of the AB light should act in the same way as if they were substantially equal; It is characterized by
従来の場合は、ABの光のみちすじもAODの光のみち
ずじも空気中にあったのであるが、上記のようにAOD
の光のみちすじの中に透明媒質20を入れると、ピント
合わせを行なう上において光のみちすじが短くなったの
と同じように作用する。In the conventional case, both the AB light path and the AOD light path were in the air, but as mentioned above, the AOD light path was in the air.
When the transparent medium 20 is inserted into the light path, it works in the same way as if the light path were shortened in terms of focusing.
すなわち、透明媒質20の屈接率がNのときは、透明媒
質20を入れた部分において光のみちすじの・長さがl
/ Hになったのと同じになる。そこで丁15ACの
長、さ分だけの光のみちすじを短くすることのできるよ
うな透明媒質20を入れてやれば、直接Q 10 aと
反射110bとを7回のピント合わせで観Y愛できるよ
うになる。That is, when the refractive index of the transparent medium 20 is N, the length of the light path in the part where the transparent medium 20 is inserted is l.
/ It will be the same as becoming H. Therefore, if we insert a transparent medium 20 that can shorten the light path by the length of 15AC, we can see the direct Q 10 a and the reflected light 110 b by focusing 7 times. It becomes like this.
透明媒g2[]には通常の光学ガラスを用いる二とがで
きる。Ordinary optical glass can be used as the transparent medium g2 [].
透明媒質20を入れる位置は、直接像を観察するのにじ

適当である。そうすれば透明tN質2()*用の支14
手段はいらないし、火花放電のときはミラー14といっ
しょに取除くことができる。The transparent medium 20 may be placed anywhere in the light path of the AOD as long as it does not interfere with direct image observation, but it is most appropriate to place it near the mirror 14. . Then, support 14 for transparent tN quality 2()*
No means are required and it can be removed together with the mirror 14 in the event of a spark discharge.
実施例(哨3図)

しである。Example (Fig. 3) The 6-light medium 20 is a prism (the material is 5p11 and li-
/, 7g1A7), and it is fixed to the mirror 14.

Just as the length of the path of AB light becomes equal to the length of the path of AOD light, the direct image 10a and the reflected beam 10b can be brought into focus at the same time.
