Plastic Coated Silica/Silica (Low OH)Anhydroguide™ AFS 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 Anhydroguide™ AFS is the
fiber of choice. The Anhydroguide™
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:

FEATURES
•Low index fluorine-doped cladding provides superior visible to infrared transmission as compared to plastic clad
fiber and borosilica clad
fiber design.•Good choice for a broad range of applications from the visible (VIS) to infrared (IR).
•Excellent for Holmium (2100nm) and Erbium (1540nm) laser delivery.
•Specialty coatings available for extreme temperature (-269°C to +700°C), high vacuum and harsh chemical environments (see Gold/Aluminum data sheets).•Laser damage resistant construction transmits 1.3kW/mm
2 CW at 1060nm; up to 10 Joules, pulsed (Special end preparation may be required).•High core to clad ratios available for high efficiency bundles (see Bundle data sheets).
•Core diameters up to 1500µm for Nylon and Tefzel™ secondary 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”.
