Gold and Aluminum FiberGold and Aluminum Coated Fiber – Metal Jacket Series/镀金/镀铝光纤

  • High Temperature Gold and Aluminum Coated Fiber

Metal coated/buffered fibers were originally developed for ultra high reliability telecommunications applications. The metal coating preserves the high initial mechanical strength and provides resistance against static fatigue (the failure under long term tensile loading), and in particular Aluminum, a hermetic coating to the fiber. In addition to high strength, metal coated fibers can be used at very high temperatures. Aluminum coated optical fibers have a rated operating range of -269°C to +400°C. Tight buffered Gold coated fibers have a rated operating range of -269°C to +700°C.

Aluminum and Gold coating can be applied on continuous lengths to a wide variety of multimode, step index, graded index, and single mode fibers.

Solarization Resistant Silica/Silica (Standard OH)/深紫外光纤

  • Cross-Section Solarization Resistant FiberDeep UV Superguide Series Fiber

Solarization is a change in material characteristics due to illumination with ultraviolet (“solar”) light. High intensities of UV illumination can cause photo-thermal damage in silica optical fibers, significantly increasing attenuation. Prolonged UV radiation, 190nm to 230nm, solarizes untreated fiber, reducing their UV transmittance significantly. The Fiberguide SolarguideTM series of fibers are perfect for long-life deep UV Spectroscopy, Lithography, Excimer laser delivery systems and for use with deuterium lamps  and an extensive range of UV laser sources below 230nm.

Most spectroscopic applications using optical fibers have been constrained to wavelength ranges above 230nm, since standard silica fibers with an undoped core and fluorine doped cladding are continually damaged by exposure to deep UV light. This Solarization effect is induced by the formation of “color centers” with an absorbance band of 214nm. These color centers are formed when impurities such as CI exist in the fiber core which is affected by deep UV radiation.

This advanced fiber manufacturing technology is made possible with recent availability of a prefabricated multimode, fused silica preform using the Plasma Outside Deposition (“POD”) process, which facilitates the creation of highly fluorine doped cladding with a depressed index compared to fused silica and hydrogen loaded proving stability in the deep UV with a slightly increased attenuation and long term stability.

Acrylate Coated Silica/Silica Tapers

  • Cross-Section Silica-Silica Taper Tapered Optical Fiber

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. Fiberguide used 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.

Graded Index Fiber

  • AGI Cross-Section Graded Index FiberSeries Fiber

Graded-index fiber refers to optical fiber that has a refractive index that gradually decreases as the distance from the core increases. This allows for multiple photonic packets to be received approximately at the same time, reducing dispersion.
