Fiberguide’s Anhydroguide™ (AFS/AFM/AFH) and Superguide™ (SFS/SFM/SFH) silica core, silica clad, polymer coated multi mode fibers are primarily used in photonics applications where individual or bundled large core (>50 µm) multi mode fibers are needed for the transmission of optical energy. These fibers can be coated with a variety of polymers or even metalized with aluminium or gold for extreme temperature performance.

While the AFS series features a low hydroxyl ion concentration (low OH) and works in the visible to IR range, SFS variants with high hydroxyl ion concentration are suitable for the UV to visible range. Options include Acrylate (-Y), Polyimide (-T), Nylon (-N), Tefzel (-Z), Aluminium (-A) and Gold (-G) coatings as well as standard (AFS/SFS), high (AFH/SFH) and low (AFM/SFM) numerical aperture.

As a further option, fibers can also 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 fiber types 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.
