  • Qualified proprietary fiber is WPI’s most advanced fiber product line.  DIN 58145:2017-01

  • Qualified fiber allows for excellent transmission of UV-NIR light in long length fiber and perform exceptionall well in the 700-2200nm wavelength region

  • Resists degradation due to UV exposure better than virtually any fiber on the market

  • Allows for true “plug and play” replacement

  • Ideal for OEM and applications requiring field service or where multiple instruments must be used for a battery of tests

  • Includes certificate and data of both UV transmission and induced loss generated by continuous exposure to a 30W deuterium bulb of each fiber material batch from 185-360nm


  • Liquid chromatrography 
  • Forensic Medicine
  • UV Raman 
  • Medical




Our QVLUX fiber has been engineered to not only provide superior transmission in the UV but have excellent consistency over length.  This makes QVLUX a perfect choice for critical measurements or where “plug-and-play” capability is required without having to recalibrate after a fiber assembly change. Our QVLUX fiber offers superior resistance to solarization, lowest basic attenuation at 200nm (<1 dB/m) and the lowest solarization at 214nm on the market.   WPI is the only company offering DIN 58145:2017-01 certified low solarization UV fiber and assemblies.
