WPI's QVLUX-series 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" capaiblity is required without having to recalibrate after a fiber assembly change. Standard silica fiber exhibits a "solarization impact" when transmitting light in the UV below ~280nm. Over time, depending on the optically transmitted power, the fiber's abiltiy to transmit UV light drops off. Our QVLUX fiber offers superior resistance to solarization, lowest basic attenuation at 200nm (<1 dB/m) and the lowest solarization at 214 nm on the market. WPI is the only companyoffering DIN 58145:2018-01 certified low solarization UV fibers and assemblies.
