The use of fiber optics in the transmission of light in the UV spectrum is gaining importance. Fields of application include, for example, the spectroscopic examination of ions and atoms; however, analytics also provides interesting application options. Further fields of application include laser medicine, such as in the treatment of psoriasis in dermatology or the correction of vision problems in ophthalmology.
The development in light sources has led to the increase in commercial interest of compact systems that offer UV fiber transmission. Inexpensive UV LEDs and UV lasers, such as excimer lasers, complement the classic range of deuterium and xenon lamps.
Fibers can be used to easily and flexibly transmit UV light for use in measurement, testing, or spectroscopy. Until not too long ago, there was one major problem with this application: In wavelengths shorter than 260 nm, UV light caused degradation in conventional fibers – a direct result of solarization effects.
Special Fibers for the UV Range
Our partner Polymicro has developed a wide range of UV-suitable fibers that can be used for very short-wave applications. The R&D department was successful in making these fibers extremely solarization proof.
Best Solarization Stability on the Market
The newly improved FDP fiber line exhibits the best solarization stability on the market.
The stabilization of the fiber material’s 214 nm and 265 nm absorption bands creates new opportunities, for example, in biomedical diagnostics, minimally-invasive surgery, or medical sensor technology in humans.
Multi-mode fibers have a core diameter between 50 µm and 1000 µm and are available at different UV grades. It is also possible to develop fibers for the single-mode UV range.
