Product information "AFS-A/SFS-A/AGI-A/ASI-A/UVS-H2A Aluminium Coated High Temperature Fibers"
Aluminium Coated, Single Mode, Multi Mode; 190 to 2400 nm; Core Diameter 50 to 400 µm; Mode Field Diameter 4.3, 9.0 µm; Cladding Diameter 125 to 440 µm; Numerical Aperture 0.12 to 0.275
Fiberguide’s AFS-A/SFS-A/AGI-A/ASI-A/UVS-H2A series of aluminium coated fibers are designed for a wide temperature range (-269 to +400 °C) and superior strength (>100 kpsi). This allows for long life at extended stress levels in applications that require tight bends. Also, the strong chemical bond between the silica cladding and the aluminum enables direct termination without pistoning.
This bond also makes aluminium coating the ideal choice to preserve deep UV performance in Fiberguide’s Solarguide UVS-H2A series of solarization resistant UV multi mode fiber.
Within this series of aluminium coated high temperature fibers, users find step index (AFS/SFS, UVS-H2) and graded index (AGI) multi mode fibers as well as anhydrous silica (ASI) single mode fibers.
As an option, some types of aluminium coated high temperature fibers can be provided with a broad selection of shaped tips – standard configurations as well as custom designed shapes. Shaped tip fibers provide optimum control over beam delivery and/or increased efficiency of light collection.
Some of the fibers can also be end capped to achieve higher coupled power into a fiber core by reducing the power density at the air / silica interface, commonly the point of laser damage. End cap diameters and lengths are offered for select numerical apertures and fiber cores size, but can be easily customized for a variety of fiber types and specialized applications.
Additionally, all fiber types can be equipped on demand with Fiberguide’s patented RARe Motheye anti-reflective technology that enhances fiber transmission performance and significantly increases the damage threshold for your application over a large wavelength range.
