> Purpose oblique wedge lens is made by Chu-precision grinding equipment, optical fiber end face grinding into the wedge ramp, after special processing means processing the optical micro-cylindrical lens at its tip, so as to achieve will become a long strip of plastic optical fiber spot with PUMP laser spot formation match. > Features traditional wedge lens need high permeability membrane coated on the end face so that the light reflectance minimum, while the oblique wedge lens because of its special geometry, making the cylindrical lens between the laser chip without affecting the optical transmission of the formation of refraction angle , reflecting fiber effectively avoid the impact caused to the life of the laser chip, also eliminates signal noise caused by reflected light. Compared with the traditional coating process to reduce the cost caused by lower yields, and long-term reliability problems caused by the coating process. > Photos> Product Performance Product parameter Fiber type single / multimode fiber HI1060 fiber customer requirements / special fiber wedge angle θ θ provided = 50 ~ 55 ° (standard) θ = 112 ± 2 ° (standard) or customer requirements (50 ~ 120 °) ± 2 ° lens radius r 4 ~ 20μm (standard) 16 ± 1μm (standard) or customer requirements ± 1μm A tip bare slim ≥0.1mm (standard) B metallization length to customer requirements ± 0.5mm C bare roots Lengthening 0mm (standard), or customer requirements ± 0.5mm D fiber stripping ± 0.5mm total length of customer requirements to customer requirements + 0.5m total length of the fiber coating thickness 3 ~ 4μm (standard) or 1 ~ 10μm (customer request) gold layer thickness ≮0.1μm Coating Rally> 5N (楚星公 Division hot solder process) Operating Temperature -55 ~ + 85 ℃ Recommended soldering temperature 280 ~ 300 ℃ recommended solder 80% Au / 20% Sn plating facet coating according to customer requirements
