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 is mainly comprised of optical fiber and fixed sturcture thereof, lens, peripheral fixture, owing to having gap between peripheral metal sleeve pipe, glass tube, and owing to having Refractive Index of Material difference and behavior error etc. between fiber core, lens, from the mechanical axis of lens emitting laser bundle and metal tube, be uneven.Therefore, when optical fiber collimator is used for to other optical device, the optical fiber collimator of two coupling uses usually needs alignment procedures specialty, complex process, and this has not only restricted the manufacture efficiency of relative photo device, is also one of reason that optical device cost is high simultaneously.Yet in some occasion, for example, for fiber rotation connector, between two optical fiber collimators, can not carry out match and regulate, this has just restricted the use of optical fiber collimator.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of novel precise optical fiber collimator is provided, and it makes optical fiber collimator have interchangeability, does not need coupling to use, and has solved the limitation of traditional fiber collimating apparatus, also the manufacture efficiency that has improved optical device, has reduced cost simultaneously.
The object of the present invention is achieved like this: a kind of novel precise optical fiber collimator, it comprises optical fiber collimator, inner sleeve and outer tube, described optical fiber collimator is arranged at inner sleeve rear end, described outer tube is set in inner sleeve outside, between described inner sleeve and outer tube, from A-P, be disposed with collimating apparatus free end fixture, hinge and collimating apparatus joint end fixture, described collimating apparatus free end fixture is positioned at outer tube front end, described collimating apparatus joint end fixture is positioned at outer tube rear end, described hinge is positioned at end fixture front side, collimating apparatus joint, described collimating apparatus free end fixture is in the form of annular discs, described collimating apparatus free end fixture center offers slit, the described slit left and right sides is provided with screw, described collimating apparatus joint end fixture is in the form of annular discs, end fixture center, described collimating apparatus joint offers through hole, described collimating apparatus joint end fixture trailing flank offers circular groove.
On described outer tube, be provided with screw, described hinge is fixed by screw.
Compared with prior art, the present invention has following beneficial effect:
A kind of novel precise optical fiber collimator of the present invention, it makes optical fiber collimator have interchangeability, does not need coupling to use, solved the limitation of traditional fiber collimating apparatus, also improved the manufacture efficiency of optical device simultaneously, reduced cost, collimator structure is simple, and ray machine right alignment is high, regulating step is few, simple for assembly process.
