Product information "UniClad™ High Power MM Fibers"
Multi Mode, High Power; 190 to 2400 nm; Core Diameter 100 to 800 µm; Cladding Diameter 500 to 1000 µm; Coating Nylon; Numerical Aperture 0.20
Fiberguide’s Universal Clad or UniClad™ series of Anhydroguide™ (AFR) and Superguide™ (SFR) high power silica core, silica clad, polymer coated multi mode optical fibers are designed for high power transmission and other applications where a large cladding relative to the core is beneficial.
The UniClad fiber series features a fixed 500 μm cladding diameter with a 100 to 400 μm core size, making laser alignment and splicing easier. The larger 600 and 800 μm core sizes use proportionally larger cladding.
While the AFR series features a low hydroxyl ion concentration (low OH) and works in the visible to IR range, SFR variants with high hydroxyl ion concentration are suitable for the UV to visible range. Both series are coated with NAMSA Class VI Nylon.
As an option, 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 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.
