UniClad™ High Power MM Fibers

300 - 2400 nm; low numerical aperture; Max Operating Temperature 85 °C; Core Diameter 50 µm; Coating Outside Diameter 250 µm Step Index multi mode fiber with pure fused silica core and fluorine doped silica cladding. With a low concentration of hydroxyl groups (OH), this fiber of the Anhydroguide™ series from Fiberguide Industries is suitable for wavelengths in the visible to infrared domain. It is primarily used in photonics applications where individual or bundled large core (> 50μm) multi mode fibers are needed for the transmission of optical energy.This “AFM” fiber features a low numerical aperture (0.12), resulting in a full acceptance angle of 14°. With a cladding diameter of 140 µm and a silicon buffer coating layer, the minimum bend radius recommended by the supplier is 13 mm (short term) or 25 mm (long term) respectively. The fibers are 100% proof tested using a 4-axis bend method with 100 KPSI. Typical applications are bio-analytical sensing, medical lasers, aerospace/defense, spectroscopy, nuclear plasma sensing or industrial laser systems.

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.

This hard coat serves as stable buffer layer that ensures a sufficient bond between the silica cladding and the polymer outer coating, making these fibers the ideal choice for a variety of medical applications. Other main application areas for the AFSH/SFSH series of hard polymer coated fibers are where individual or bundled large core (>50 µm) multi mode fibers are needed for the transmission of optical energy.

Fiber Type Single Mode, Multi Mode Step & Graded Index; Input Core Diameter 100 to 600 µm; Output Core Diameter 50 to 200 µm; Numerical Aperture 0.12, 0.26; Wavelength 180 to 2400 nm; Sheathing PVC, Stainless Steel Fiberguide’s AFT/SFT series of optical tapers are used for mode mixing, lowering optical power density in high power applications, and converting numerical aperture (NA) in optical power delivery applications. Optical tapers can either be tower drawn, where the length is several meters, or they can be produced using bench-top equipment, making the length a few inches. In both cases, these optical tapers are continuous pieces of fiber, they are not spliced. Tapered optical fibers can be made either by fusing a short tapered section onto a longer fixed diameter fiber or by very carefully controlling the drawing process to produce a single continuous fiber with an integral tapered section. For its AFT/SFT series, Fiberguide uses the latter process since it results in superior fiber strength, alignment precision and optical power transmission. Tapered optical fibers cause optical mode mixing that tends to homogenize spatial power distribution. A larger input core diameter can prevent input damage and allow a smaller diameter pigtail for convenience in adapting to a wide range of optical applications. Tapered optical fibers can be used as a passive optical component to alter the input and / or output divergence (N.A.) with regard to an optical fiber, as a high power coupler for laser energy, as this will spread the energy over a larger area, or simply as a device to relax tolerances in an optical system. To ensure maximum efficiency of light transmission, the numerical aperture (N.A.) of the light entering the taper input should be 0.22 divided by the taper ratio. As an example, assume the input core diameter of the taper is 400 µm and the output core is 200 µm (2:1 taper ratio), then the N.A. of the light entering the taper will be 0.22/2 = 0.11. Additionally, the fibers 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.

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.

The uniform “top hat” intensity profile these fibers provide are the desired output profile when performing tasks such as welding, photolithography, and spectroscopy. Square core fibers with round claddings are also excellent candidates for use in the laser diode industry, where the square shape enables a more ideal coupling match with the diode source. Fiberguide offers pure silica square core fibers with a fluorine doped cladding (0.22 NA) in a wide range of core diameters from 100 μm to 1000 μm. While the ASQR series features a low hydroxyl ion concentration (low OH) and works in the visible to IR range, SSQR variants with high hydroxyl ion concentration are suitable for the UV to visible range.
