Technical field
The present invention relates to a kind of optical fiber collimator and its assemble method with high accuracy ray machine axiality.
Background technology
In optical fibre device, optical fiber collimator is a kind of Primary Component.Traditional optical fiber collimator, as shown in figure 1, it leads
If being made up of optical fiber and its fixed structure, lens, peripheral fixture, between existing between peripheral metal sleeve pipe, glass tube
Gap, and due to there is Refractive Index of Material difference and behavior error etc. between fiber core, lens, from the laser beam of lens outgoing
It is not parallel with the mechanical axis of metal tube.Therefore, when optical fiber collimator is used for into other optical devices, two match what is used
Optical fiber collimator usually needs specialty, complex process alignment procedures, and this not only constrains the manufacture efficiency of related optical device,
One of the reason for being also simultaneously optical device high cost.But in some occasions, for example, in for fiber rotation connector, two
Can not carry out matching regulation between individual optical fiber collimator, this just constrains the use of optical fiber collimator.
The content of the invention

In outer tube rear end, the hinge is located at collimater joint end fixture front side, and screw, the hinge are provided with the outer tube
Chain is fixed by screw.
Slit is offered on the fixture of the collimater free end, the slit width is slightly larger than collimator adjustment inner sleeve
The diameter of pipe.
A kind of assemble method of the optical fiber collimator with high accuracy ray machine axiality, the described method comprises the following steps：
Step one, collimater free end fixture is packed into inner sleeve；
Step 2, the position for regulating inner sleeve；
Step 3, rotary collimator free end fixture adjustment slit direction, make the collimater free end fixture can be along narrow
The movement of seam direction；
Step 4, by the cylindrical hole of collimater free end fixture insertion outer tube front end, it is then temporary transient with trip bolt
Fixed collimater free end fixture；
Step 5, using laser welding, inner sleeve is fixed on the fixture of collimater free end；
Step 6, collimater free end fixture and collimater joint end fixture are welded by the means of laser welding
Onto outer tube.
Compared with prior art, the invention has the advantages that：
The present invention a kind of optical fiber collimator and its assemble method with high accuracy ray machine axiality, it makes optical fiber collimator
With interchangeability, need not match and use, the limitation of traditional fiber collimater be solved, while also improving the system of optical device
Efficiency is made, cost is reduced, collimator structure is simple, and ray machine axiality is high, and regulating step is few, simple for assembly process.
