Level.
Generally, fiber array is made up of glass V-groove, glass cover-plate, optical fiber and fixed glue, and glass V-groove is made
For the positioning device for accuracy of optical fiber, its spacing precision reaches 0.5 micron, when optical fiber is put into V-groove, with cover plate pressed fiber,
Make two inclined-planes of close fiber optic and V grooves tangent, so that it is guaranteed that optical fiber arrangement has the spacing accuracy same with V grooves.Generally, cover plate
Thickness is in 0.5mm~1mm, but in some special occasions of optical fiber sensing system, because fiber array need with corresponding part without
Seam docking uses, it is desirable to can not have cover plate, in this case, existing fiber array mounting technology such as without cover plate pressuring action,
It is the precision for being difficult to ensure that optical fiber arrangement.
In summary, in some special application scenarios, it is necessary to use the fiber array of no cover plate, but existing optical fiber array
Row technology is difficult to ensure that the precision of its optical fiber arrangement in the case of without cover plate.

As shown in Figure 1, 2, the fiber array for a kind of no cover plate that this implementation provides, including：Bottom plate 1 and optical fiber 2, bottom plate 1
One side be vertically arranged with multiple row V-groove 11, V-groove 11 is arranged on one end of bottom plate 1, and length is the 1/3~1/ of the length of bottom plate 1
2, one end of bottom plate 1 is provided with step 12, and the front end of optical fiber 2 has divested coat and has been partly embedded into V-groove 11, and fixed glue A will
Together with the tight bond of V-groove 11, optical fiber 1 and step 12 are then bonded together optical fiber 2 by fixed glue B, are risen and are strengthened optical fiber
Bond protective effect.
The assembling without cover plate fiber array of the application uses one using the conventional assembling device for having cover plate fiber array
The individual glass cover-plate 3 with specific coatings, this specific coatings are nonwettable to fixed glue A and fixed glue B, work as solidification glue
Will not be together with glue bonding during water, while this specific coatings are very thin, are translucent.Specific installation step is as follows：
Step 1：Glass V-groove is subjected to ultrasonic wave cleaning and dried；
Step 2：Glass V-groove is put into assembly tooling and fixed；
Step 3：The front end of optical fiber is divested into a bit of coat, length requirement is divested and is about 5mm than V-groove；
Step 4：Optical fiber front end is divested into coat part to be put into V-groove, optical fiber afterbody is temporarily solid with one-faced tapes
It is scheduled on fixture；
Step 5：The position before and after optical fiber is adjusted, optical fiber coating is peeled off intersection apart from the position of step rear end about 1/3；
Step 6：The glass cover-plate with specific coatings is put into above V-groove, downward pressed fiber is until optical fiber enters completely
Enter in V grooves；
Step 7：Glue A is fixed in bottom plate step inclined plane part site, after glue A to be fixed fills V grooves, with UV optic-solidified adhesives
Water A；
Step 8：Point fixes glue B at bottom plate step, with UV photocuring glue B；
Step 9：The glass cover-plate with specific coatings is removed, removes the fiber array of no cover plate；
Step 10：Being put into high temperature oven without cover plate fiber array and being toasted for assembling will be completed, baking temperature at 85 DEG C,
Time is 2 hours, with thorough solidified glue；
Step 11：End surface grinding and polishing are carried out to the fiber array for completing assembling；
Step 12：Check fiber array face machined flat.
The application without cover plate fiber array, there is the same fiber orientation precision with cover plate fiber array, can meet
The requirement of some particular applications, while existing assembly tooling and similar assembly technology are used, using only with special painting
The glass cover-plate of layer replaces conventional glass cover-plate, thus can realize high-precision no cover plate fiber array at lower cost.
