Anti-Solarization
The transmission of conventional UV-enhanced silica/silica fiber decreases rapidly at wavelengths below 240 nm when exposed to high intensities of a deuterium lamp. This effect is called “UV-solarization” and results from the generation of color centers in the fiber material. The lifetime of such a fiber, defined by the 1/e reduction in transmission at 240 nm, is normally less than 200 minutes. This effect renders them unsuitable for UV spectroscopy below 240 nm. Anti-solarization fibers suitable for deep UV spectroscopy solve this problem. These fibers stabilize to less than 5% degradation over a period of 20,000 hours after an initial transmission “burn-in” loss of less than 25%. Additionally, this anti-solarization characteristic will not degrade over time.
