j-fiber introduces its new j-Ultrasol solarization resistant optical fiber
86% long term high transmission stability under UV exposure for <400nm wavelengths for 1500h applications in spectroscopy and medical or industrial components
Jena, June 15, 2009 – Highest transmission stability, long fiber life time: Ultraviolet radiation exposure impacts the transmission performance and life time of silica fibers. With j-Ultrasol j-fiber has developed a solarization resistant fiber for long life, high transmission stability under UV exposure, specifically in the critical sub 230 nm range. j-Ultrasol fiber thereby shows excellent short, mid and long-term stability results under UV exposure (215 nm deuterium lamp with an optical output of 8 µ W): 93% transmission short-term stability over the first 2 h; for up to 240 h of UV exposure the fiber shows only a moderate stability decline from 93% to 86%, a transmission stability level that j-Ultrasol reliably maintains during the tested 1500 hours under UV exposure.
j-Ultrasol High Transmission Stability
Relative transmission curve of j-Ultrasol fiber at 215 nm (step-index fluorine doped fiber, 200/220 µm, NA 0.22) 229 nm and 265 nm wavelengths as a function of the deuterium lamp exposure time up to 1500 hours.
Optimized for <400 nm wavelength applications: The 200 µm silica core, 220 µm fluorine-doped silica clad Step Index Multimode fiber has been designed for spectroscopy and medical or industry applications in the < 400 nm wavelength operation range. Other core/clad diameters are available upon request.
Superior fiber performance based on complete value chain competence: Through the capabilities within our vertically integrated process chain, including our own silica production, preform design and manufacturing, and the final fiber drawing process, we can ensure sustained fiber performance and minimize solarization specific performance degradation - already by controlling the raw material and preform processes from the very beginning.
