Solarization Resistant Multimode fibers
Highest transmission stability, long fiber life time
Ultraviolet radiation exposure impacts the transmission performance and life time of silica fibers. The shorter the wavelength and the higher the intensity and duration of exposure the shorter is the fiber life time.
With j-Ultrasol and j-Lowsol j-fiber has developed a product line of solarization resistant preforms and fibers to increase fiber resistance to UV exposure and meet application specific fiber life and transmission stability requirements under UV exposure – specifically in the <400nm range.
j-Ultrasol
j-Ultrasol for long term transmission stability and long life time applications: With j-Ultrasol, j-fiber has developed a solarization resistant fiber for long life, high transmission stability under UV exposure, especially in the critical wavelength range below 230 nm. j-Ultrasol shows excellent short and long-term stability results: 96% transmission stability at 215 nm over short-term (<24 h) UV exposure, long-term high transmission stability (<1500 h) at a steady 86% level. The silica core/fluorine-doped silica clad Step Index Multimode fiber is well suited for spectroscopy and medical and industry applications in the wavelength operation range below 400 nm.
Applications with long term fiber transmission stability demands in:
- Spectroscopy
- Mecial devices
- Industry applications
- Ultra high tansmission stability under UV exposure (215nm deuterium lamp, optical output 8µW)
