Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
No glue optical fiber collimator; Include optical fiber head, the collimator lens 3 of optical fiber 1 and kapillary 2 compositions and be used for fixing optical fiber head and the sleeve pipe 4 of collimator lens 3 positions; Also comprise the solder structure that constitutes with the soldered mode; Said optical fiber 1 light output end and kapillary 2 tops are solder structure, and the coupling part of said collimator lens 3 and sleeve pipe 4 is a solder structure, and the coupling part of said optical fiber head and sleeve pipe 4 also is a solder structure.
As depicted in figs. 1 and 2, for making the synoptic diagram of optical fiber head.Wherein, Fig. 1 is placed on the part that optical fiber 1 light output end exceeds kapillary 2 tops for adopting the method for low temperature glass solder with low temperature glass solder 8, adds auxiliary heating quoit 9 in glass solder 8 outsides; The temperature that heats the auxiliary heating quoit 9 that raises through electromagnetic type is more than the fusing point that reaches low temperature glass solder 8; Heat is passed to glass solder 8 through transmittance process, and glass solder 8 will reach molten state, cuts off the electromagnetism heating source; Glass solder 8 will transfer solid-state low temperature glass circle 8 to from molten state, and firmly that optical fiber 1 is fixing with kapillary 2 simultaneously.The effect that optical fiber 5 is not in the mood in optical fiber 1 top welding is the logical light area that increases laser beam, to improve the damage threshold that destroys.The bottom of kapillary 2 also can be fixed through the mode of low temperature glass solder 8.
Fig. 2 is the method that adopts the scolding tin welding.At first optical fiber 1 top outer and kapillary 2 tops are carried out gold-plated 6 and handle, through scolding tin 7 the two firmly is fixed together then.
The optical fiber head of making also need carry out the oblique angle to the top and handle, and the pitch angle is about 6 degree to 8 degree, at last optical fiber head is carried out coating film treatment.As shown in Figure 3.
Like Fig. 4 and shown in Figure 5, for collimator lens 3 and optical fiber head being fixed in the method for sleeve pipe 4.Wherein, Fig. 4 is for adopting the method for low temperature glass solder 8.Collimator lens 3 is exceeded the part of sleeve pipe 4 and part that optical fiber head exceeds sleeve pipe 4 is placed glass solder 8 respectively; Outside glass solder 8, add auxiliary heating quoit 9; The temperature that heats the auxiliary heating quoit that raises through electromagnetic type is more than the fusing point that reaches low temperature glass solder 8, and heat is passed to glass solder 8 through transmittance process, and glass solder 8 will reach molten state; Cut off the electromagnetism heating source; Glass solder 8 will transfer solid-state low temperature glass circle 8 to from molten state, realizes collimator lens 3 fixing with sleeve pipe 4, simultaneously that optical fiber head and sleeve pipe 4 is fixing.
As shown in Figure 5; For adopting the mode of scolding tin welding; Part and sleeve pipe 4 two ends end faces that part, the optical fiber head that earlier collimator lens 3 is exceeded sleeve pipe 4 exceeds sleeve pipe 4 carry out gold-plated processing; Scolding tin 7 is handled on gold-plated 6 again, and collimator lens 3 is fixing with sleeve pipe 4, and is simultaneously that optical fiber head and sleeve pipe 4 is fixing.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; In form with on the details the utility model is made various variations, be the protection domain of the utility model.
