APC/SPC Polymer Clad MM Fibers

Product information "APC/SPC Polymer Clad MM Fibers"

Multi Mode; 190 to 2200 nm; Core Diameter 200 to 2000 µm; Cladding Diameter 300 to 2150 µm; Coating Nylon; Numerical Aperture 0.37

Fiberguide’s Anhydroguide™ (APC) and Superguide™ (SPC) series of silica core, polymer clad, Nylon coated multi mode fibers feature a polymer cladding. This polymer cladding enables a numerical aperture (NA) of 0.37, but it differs from the hard polymer cladding of Fiberguide’s APCH/SPCH series of hard polymer clad MM fibers because the polymer cladding offers better radiation stability for nuclear research and sensing applications.

While the APC series features a low hydroxyl ion concentration (low OH) and works in the visible to IR range, SPC 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.

APCH/SPCH Hard Polymer Clad MM Fibers
Multi Mode; 190 to 2200 nm; Core Diameter 200 to 1500 µm; Cladding Diameter 230 to 1550 µm; Coating Tefzel (Natural & Blue); Numerical Aperture 0.37Fiberguide’s Anhydroguide™ (APCH) and Superguide™ (SPCH) series of silica core, hard clad fibers feature a hard polymer cladding instead of a silica cladding. This hard polymer cladding enables a higher numerical aperture (NA, 0.37) than a silica cladding and reduces cost. Hard clad fibers like the APCH/SPCH series are the ideal choice for disposable medical products. While the APCH series features a low hydroxyl ion concentration (low OH) and works in the visible to IR range, SPCH variants with high hydroxyl ion concentration are suitable for the UV to visible range. Options include natural (-Z) or blue (-C) Tefzel coatings. As an option, fibers can be provided with a broad selection of shaped tips – standard configurations as well as custom designed shapes.
