Then, by heat-curable epoxy resin 28 gasket ring 29 is adhered on the other end 22b of gradually changed refractive index lens 22.Further, by heat-curable epoxy resin 28 optical filter 24 is adhered on the gasket ring 29.In the first embodiment of the present invention, the thickness of above-mentioned gasket ring is that 0.18mm, external diameter are that 1.8mm and internal diameter are 1.2mm.By the capillary principle, heat-curable epoxy resin is adsorbed between gasket ring and the gradually changed refractive index lens equably.Heat-curable epoxy resin can not infiltrate in the ring of gasket ring, so heat-curable epoxy resin can not disturb the light beam by gasket ring.
Second embodiment
In Fig. 4, show the optics collimator of the second embodiment of the present invention.As shown in Figure 4, this optics collimator 30 comprises a glass lasso 31, gradually changed refractive index lens 32, two gasket ring 39a, 39b and an optical filter 34.Above-mentioned glass lasso 31 has a hole 31a, and an optical fiber 35 is set in hole 31a.
Then, by heat-curable epoxy resin 38 gasket ring 39b is adhered to an end face 32a of gradually changed refractive index lens 32.Further, by heat-curable epoxy resin 38 glass lasso 31 is bonded on the gasket ring 39b.Then, by heat-curable epoxy resin 38 another gasket ring 39a is bonded on the other end 32b of gradually changed refractive index lens 32.Further, by heat-curable epoxy resin 38 optical filter 34 is adhered on this gasket ring 39a.Therefore, has both gap 37 of set a distance between glass lasso 31 and the gradually changed refractive index lens 32.
In the second embodiment of the present invention, the thickness of above-mentioned gasket ring is all 0.18mm, external diameter is that 1.8mm and internal diameter are 1.2mm.By the capillary principle, heat-curable epoxy resin is adsorbed between gasket ring and the gradually changed refractive index lens equably.Heat-curable epoxy resin can not infiltrate in the ring of gasket ring, so heat-curable epoxy resin can not disturb the light beam by gasket ring.
The 3rd embodiment
In Fig. 5, shown the optics collimator of the third embodiment of the present invention.As shown in Figure 5, this optics collimator 40 comprises a glass lasso 41, gradually changed refractive index lens 42, two gasket ring 49a, 49b and an optical filter 44.Above-mentioned glass lasso 41 has a hole 41a, and one first optical fiber 45a and one second optical fiber 45b are set in hole 41a.
Then, by heat-curable epoxy resin 48 a gasket ring 49a is adhered on the end face 42b of gradually changed refractive index lens 42.Further, by heat-curable epoxy resin 48 optical filter 44 is adhered on this gasket ring 49a.One go on foot again, another gasket ring 49b is adhered to the other end 42a of gradually changed refractive index lens 42 by heat-curable epoxy resin 48.At last, by heat-curable epoxy resin 48 glass lasso 41 is adhered on this gasket ring 49b.Therefore, has both gap 47 of set a distance between glass lasso 41 and the gradually changed refractive index lens 42.
Before the heat-curable epoxy resin between glass lasso and the gradually changed refractive index lens is uncured, said structure is erected on the adjusting mechanism; Wherein, the gradually changed refractive index lens are arranged on the fixed mount, and the glass lasso is arranged on the First Five-Year Plan axial adjustment member.One broadband light beam is imported above-mentioned first optical fiber, and this broadband light beam enters the gradually changed refractive index lens from the emission of first optical fiber.Then, this broadband light beam reflects a folded light beam by optical filter after the emission of gradually changed refractive index lens.This folded light beam will enter above-mentioned second optical fiber by the gradually changed refractive index lens.By the position of above-mentioned five axial adjustment members adjustment glass lasso,, fix five axial adjustment members when when second optical fiber obtains best reflected light beam signal.Further, by the heat curing epoxy resin between heating glass lasso and the gradually changed refractive index lens, make glass lasso, gasket ring and gradually changed refractive index lens closely bonding.
In the third embodiment of the present invention, the thickness of above-mentioned gasket ring is that 0.18mm, external diameter are that 1.8mm and internal diameter are 1.2mm.By the capillary principle, heat-curable epoxy resin is adsorbed between gasket ring and the gradually changed refractive index lens equably.Heat-curable epoxy resin can not infiltrate in the ring of gasket ring, so heat-curable epoxy resin can not disturb the light beam by gasket ring.
In Fig. 6, shown the gasket ring that uses at optics collimator of the present invention.As shown in Figure 6, in an embodiment of the present invention,, can obtain minimum penetration loss (transmission loss) by the thickness t that changes gasket ring 100.In Fig. 7, shown the different shape of gasket ring.As shown in Figure 7, the shape of gasket ring can be circular, square or the hollow geometry of polygon.
In the present invention, above-mentioned gasket ring can utilize that metal, glass or other heatproof are indeformable more than 200 ℃ a made.
In the present invention, capillarity is because due to the surface tension between very little two planes, gap.When the heat-curable epoxy resin heating, behind the liquid state that thins out, because capillarity, heat-curable epoxy resin can be toward the gasket ring central permeate.When being penetrated into the inner ring hollow region of gasket ring, can stop because of capillary reduction.In addition, because capillarity makes that gasket ring is able to fully fully contact with gradually changed refractive index lens and filter plate, and make that then intensity significantly promotes.Therefore, capillarity is useful to the present invention, but not shortcoming.
Though the present invention discloses as above with preferred embodiment; right its is not in order to limit the present invention; anyly have the knack of this skill person; without departing from the spirit and scope of the invention; when can doing to change and retouching, so protection scope of the present invention is as the criterion when the scope that claim was defined with patent claim.
