Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
The operation wavelength of the transmission laser that this fiber transmission device adopts is between 308nm-2940nm, the laser of this wavelength period all can transmit with existing optical fiber or special fiber, can satisfy the special applications of aspects such as industry, detection, medical treatment, especially practical more aspect medical applications, can with the supporting use of endoscope, to tissue solidify, vaporization and cutting etc.The utility model operation is simple and easy, with clearly defined objective, and structure and processing are simple, and cost is low, promotes the use of easily.
As shown in Figure 1, this fiber transmission device can change the transmission direction of light, is made up of optical fiber 1, the joints of optical fibre 2, fiber optic protection cover 3, bright dipping indicating label 4, positioning of rotating cover 5 etc.Described fiber transmission device is the optical fiber 1 that can transmit from the ultraviolet light to the infrared light; input end is fixed with the joints of optical fibre 2; output terminal is fixed with fiber optic protection cover 3, and wherein optical fiber 1 output end is made into the inclined-plane 8 of certain angle, and positioning of rotating cover 5 is enclosed within on the described optical fiber 1.Light is from the input of optical fiber 1 input end, and through Optical Fiber Transmission, light changes transmission direction by optical fiber 1 terminal inclined-plane 8, forms angle output with the fiber optic hub axle, thereby changes the transmission direction of light.
At first, laser is that this end of connector from optical fiber is coupled into, and the joints of optical fibre 2 adopt the connector (ST, SC, FC, SMA etc.) or the non-standard connector of standards, all can reach coupling effect.Laser coupled is come in, and transmits in optical fiber, and in order to change the transmission direction of laser, we process the end of laser, is processed into 29 °-45 ° angle, and polishes.The angle of inclined-plane 8 and shaft axis of optic fibre is by the refractive index of optical fiber, and the numerical aperture NA of optical fiber and the pattern of incident light determine that inclined-plane 8 angles must meet the total reflection principle of light, could obtain best light extraction efficiency.For NA is 0.22 optical fiber, the laser of transmission 532nm wavelength, and through calculation optimization, this angle is 29 °-45 °, optical fiber is processed into this angle, the fiber transmission attenuation minimum.
Optical fiber connector is processed to the inclined-plane, and the end face attenuation comes to a point, and transmission is easy to be burnt during high power laser, and optical fiber is also very easy simultaneously breaks and pollute.The fiber optic protection cover plays the effect of protection optical fiber exactly, does not also influence the transmission of laser simultaneously.Fiber optic protection cover 3 is made by optical clear glass (crystalline quartz, fused quartz, sapphire, calcium fluoride etc.), and length is between 5mm-30mm, and for cylindrical, the bottom is a circular seal, interior hollow, and internal diameter is bigger slightly than optical fiber core diameter.The bottom that fiber optic protection cover 3 usefulness glue sealing and fixing are not run into protective cover 3 on optical fiber connector optical fiber connector inclined-plane.Like this, optical fiber connector is just sealed by fiber optic protection cover 3, play dustproof, anti-collision, and play the total reflection effect.Thereby, realize the purpose of this novel practical.
As Fig. 2, for can be exactly the effect of light that changes laser direction on target, we stick a bright dipping indicating label 4 again on the surface of fiber optic protection cover 3.Bright dipping indicating label 4 adopts transparent materials to make, and indicates red bright dipping cue mark " * " above, and the reverse side of light direction indicates blue markings " ● ", i.e. and " filled circles ", and bright dipping indicating label 4 sticks between protective cover 3 and the optical fiber 1.
Simultaneously, for easy to operate, as Fig. 3, design has positioning of rotating cover 5 on the optical fiber between the terminal 38mm-50mm of distance fiber optic protection cover.The profile of positioning of rotating cover 5 is circular straight knurling, axially is through hole, and through-hole diameter is bigger than optical fiber 1 profile diameter slightly.The profile of positioning of rotating cover 5 has one to protrude mark 9, and it is consistent with bright dipping indicating label 4 directions to protrude mark 9, so just can accurately grasp the bright dipping aspect, avoids accidental operation.
With glue be adhesively fixed place between distance fiber optic protection cover 3 terminal 38mm-50mm of positioning of rotating cover 5 and optical fiber.This distance will with the matching used instrument of optical fiber, match as endoscope, ureteroscope etc.
Between fiber connector 2 and positioning of rotating cover 5, optical fiber overcoat one optical fiber jacket 6.Optical fiber jacket 6 is connected with fiber connector 2, positioning of rotating cover 5.The optical fiber jacket 6 of this novel practical has outside the protection fiber functions of general optical fiber; importantly can also protect laser overflows from the optical fiber wall; during the Optical Fiber Transmission high power laser; avoid eyes to suffer radiation; and have and slow down and loosen the distortion that the The of optical fiber institute is subjected to; avoiding optical fiber to be turned round the effect of damage, is that the green optical maser wavelength of 532nm is that the yellow optical maser wavelength of 589nm is the red laser of 635nm and 659nm for visible light such as wavelength, and eyes can not see that laser has any leakage from sheath 6.
