Optical Fibers

WPI can build custom fiber optic assemblies for many UV (ultraviolet), VIS (visible light spectrum) and NIR (near infra red) applications. If you don't find what you are looking for here, give us a call and speak with one of our specialists.

 Optical fibers for spectroscopy applications

 

Anti-Solarization

The transmission of conventional UV-enhanced silica/silica fiber decreases rapidly at wavelengths below 240nm when exposed to high intensities of a deuterium lamp. This effect is called UV Solarlization. It results from the generation of color centers in the fiber material. The lifetime os such an optical fiber, defined by the 1/3 reduction in transmission at 240nm, is normally less than 200 minutes. This effect renders them unsuitable for UV spectroscopy below 240nm. 

Anti-solarization fibers suitable for deep UV spectroscopy solve this problem. These fibers stabilize to less than 5% degradation over a period of 20,000 hours after an initial transmission "burn in" loss of less than 25%. Additionally, this anti-solarization characteristic will not degrade over time.

Bifurcated Fibers

Use bifurcated fibers to combine similar intensity light from differing sources or to split a light source into two fibers. These are for use with a dual spectrometer as a reference.

Plastic Fibers

Plastic optical fibers are more flexible than glass fibers. These inexpensive PMMA plastic fibers may be used for illumination and scientific applications. They are excellent for light transfer between 350nm and 1000nm. Their maximum temperature should be kept below 80°C.

Standard UV/VIS Optical Fibers

Our standard optical fibers have broad UV and VIS spectral range. They are resistant to laser damage. They have a high core-to-clad ratio. The are composed of bio-compatible material and offer a broad temperature range for operation. They offer higher transmission than PCS between 180nm and 300nm.
