Plastic Coated Silica/Silica (Standard OH)Superguide™ SFS Fiberguide Industries Technical Data

DESCRIPTION REFERENCE SUMMARY

When looking for a high quality fiber with superior transmission and a numerical aperture (N.A.) of 0.22 for efficient light coupling, the Superguide™ SFS is the fiber of choice. The Superguide™ fiber is drawn from preforms manufactured by the Plasma Outside Deposition (POD) process. Rods of extremely pure synthetic fused silica are coated with fluorine doped silica layers to obtain preforms with step-like refractive index profiles. Plasma torches prepare the reaction compounds from SiCl Product Category: Fiber
4, O
2 , and a fluorine containing gas. Strong thermal gradientscombined with the temperature plasma lead to chemical deposition conditions, which allow very high fluorine concentrations to be incorporated in the fused silica network. Refractive index differences of 0.27 corresponding to numerical apertures in excess of 0.28 have been realized with undoped core rods. Mode: Step Index, Multimode Type: Plastic Coated Silica/Silica (Standard OH)

FEATURES

•Low loss and the finest fiber for ultraviolet (UV) through visible (VIS) applications. •Specialty coatings available for extreme temperatures, high vacuum, and harsh chemical environments(see Gold/Aluminum data sheets).•Highest laser damage resistance for Nd:YAG, HeNe, Argon-Ion, and Excimer laser delivery. •High core to clad ratios available for high efficiency bundles (see Bundle data sheets).•Core diameters up to 1500µm for Nylon and Tefzel™ buffers.•Sterilizable ETO, steam, e-beam, gamma radiation. •Radiation resistant. •All dielectric, non-magnetic construction. •Polyimide buffer resists most organics, solvents and acid. •12µm to 15µm thick Polyimide buffer allows for the manufacture of high packing efficiency arrays and bundles(please see Fiber Optic Assembly data sheet).•Polyimide buffer is heat sterilizable (autoclave). Note: If the buffer/jacket material has a lower refractive index than the cladding, as is the case for silicone coatedsilica/silica fibers, then optical energy can be guided within the cladding. The high refractive index of Polyimide and Acrylate effectively strips out these “cladding modes”.
