Fiberguide’s Plastic Clad Silica Fibers Offer Excellent UV and Infrared Transmission

Low and standard OH fibers feature plastic cladding to prevent fiber breakage

Stirling, N.J. (April 19, 2010) – For medical, scientific and military applications, Fiberguide Industries offers a full line of low and standard hydroxyl concentration (OH) plastic coated silica fibers.  The Anhydroguide™ and Superguide™ are low cost optical fibers that provide superior UV and infrared transmissions.

Fiberguide’s Anhydroguide fiber is constructed of a pure fused silica core, made by reacting silicon tetrachloride with oxygen using a plasma arc.  This ensures a low residual OH for excellent infrared transmission.  Superguide’s silica core is constructed in the same manner, only with an oxy-hydrogen flame instead of a plasma arc, which maximizes the fiber’s UV transmission properties.

Both fibers feature plastic cladding to protect the fiber during buffer stripping and prevent breakage, while increasing fiber strength and reducing static fatigue in humid environments.  Fibers offer exceptional transmission in tight bends, with a high core-to-clad ratio and numerical aperture of 0.37.  All materials used in construction are certified by NAMSA to USP Class VI for non-toxicity and biocompatibility.

Fiberguide’s Multimode Fibers Provide Accurate High Power Laser Delivery

Lightweight and flexible optical fibers eliminate heavy articulated arms

Stirling, N.J. (January 11, 2010) – Delivery of high power laser light in scientific, military, and industrial/ commercial applications normally requires bulky, inconvenient and often heavy articulated arms.  For a more efficient approach to laser delivery, Fiberguide Industries offers its multimode, step-index optical fibers.

Fiberguide's multimode fibers for high power laser delivery.

Fiberguide’s multimode fibers are a simple way to accurately deliver high power laser beams.  They feature an air-gap design, where the fiber extends into free space.  This provides an epoxy-free region where thermal energy can be safely dissipated without burning the surrounding material, a common cause of failure in standard connectors.  To maximize power handling and beam uniformity, fiber end surfaces are cleaved and then laser polished to eliminate contaminants, scratches, chips and pits.

Standard core diameters of 100µ, 200µ, 300µ, 400µ, 600µ, 1000µ and 1500µ are available, with non standard diameters available upon request.  To aid in the correct fiber diameter selection for each particular application, Fiberguide’s new data sheets provide updated technical information.  To download a data sheet, visit the following link: http://fiberguideindustries.thomasnet.com/Asset/HighPower%2012-02-09.pdf.

Fiberguide's polyimide coated fibers for high temperature performance.

Fiberguide’s polyimide coating is ideal for oil and gas, aerospace, sensors, defense, medical and security applications requiring high temperature resistance.  The coating withstands operating temperatures up to 400ºC (300ºC continuous), while conventional coatings such as acrylate, nylon and Tefzel® begin to deteriorate between 100ºC and 250ºC.  

Additionally, Fiberguide’s unique process of applying the coating results in a fiber of significantly reduced cross-sectional area.  This low profile characteristic is optimal for use in bundles and supports spectral transmission from 160nm to 2500nm.

Polyimide coated fiber is available in step index, multimode fibers from 50um cores to 600um cores; 6.25um/125um and 50um//125um graded index; and 4.8um/125um and 9.2um/125um single mode fibers.  The fiber offers high performance optical and mechanical specifications with tight dimension tolerances providing high uniformity and lot-to-lot consistency.

Solarization Resistant Fibers from Fiberguide Industries

Fibers’ coating protects against solarization during deep UV exposure

Stirling, N.J. (July 21, 2009) – Leading optical fiber manufacturer Fiberguide Industries has introduced a full line of standard solarization resistant fibers for deep UV applications.  The fibers are ideal for spectroscopy, lithography and excimer laser delivery applications where fibers are exposed to deuterium lamp transmission (190nm to 230nm) or ArF-Excimer (193nm) laser.

Fiberguide Industries’ solarization resistant fibers

Prolonged UV transmission below 260nm causes solarization in optical fibers, reducing their UV transmittance significantly.  Fiberguide’s solarization resistant fibers use a modified core preform that protects fiber from the damaging effects of deep UV.  These fibers have excellent performance and long-term stability at 30 to 40% transmission (for 215nm).  Fiber core sizes can be produced from 50um to greater than 1000um.  Custom cabled or multi-fiber assemblies are also available.

Fiberguide Introduces Collimators and Focus Guides for Fiber Optics

Modules efficiently collimate a power light source into a defined degree beam

Stirling, N.J. (February 10, 2009) – Leading optical fiber manufacturer Fiberguide Industries has introduced a line of standard collimators and focus guides for use with a wide variety of optical systems.

Collimators and focus guides from Fiberguide

Designed to collimate or focus light exiting an optical fiber to a desired beam diameter, the collimators can be used with laser diodes, photodiodes, acoustic-optic modulators and other fiber optic devices.  Focus guides thread into the collimator, refocusing the beam at a given distance.  Collimators and focus guides can be used as matched pairs to couple light in and out of optical devices.

The ruggedized modules are manufactured to accept SMA, ST, FC or machined ferrule style connectors.  Assembled and preset to meet required specifications, all collimators and focus guides can be adjusted to provide the flexibility necessary for customers’ specified set ups.

Collimators are available in three sizes: the macro collimator for optical fiber core sizes larger than 800μm diameter, the mid-size collimator for sizes up to 800μm diameter, and the micro collimators for fibers up to 400μm diameter.  Focus guides are available for the macro and mid-size collimators.

Mode Scrambler Option Eliminates High Power Laser Hot Spots

SMA connector removes all energy absorbing materials at fiber end

Stirling, N.J. (November 12, 2008) – Fiberguide Industries’ new mode scrambler option for its line of high power laser delivery assemblies protects the fiber optic conduit by conducting heat away from the fiber end.  Incorporated into the proximal end of the laser assembly, the mode scrambler allows the laser beam a homogeneous exit.

Fiberguide’s mode scrambler

The assembly option employs a custom designed high-power SMA connector, which utilizes air gap technology to eliminate all energy absorbing materials at the fiber end.  The cantilevered fiber end can accept very high power levels that would normally destroy traditional fiber termination.  A uniquely designed heat sink is thermally and mechanically connected to the assembly to effectively conduct generated heat away from fiber.

The mode scrambler option is offered on Fiberguide’s standard silica and hard clad fibers, in standard core diameters from 200 to 1500um with numerical apertures ranging from 0.12, 0.22 (standard), 0.26 and 0.39 (standard).  For high power levels, a high conductivity copper ferrule is used for the nose of the connector allowing for greater heat dissipation.  All systems are designed around customers’ exacting requirements and specifications.
