Setting new standards through breakthrough research and development is at the heart of our business. As the manufacturer of one of the world's best UV Low-Solarizing optical fiber, CeramOptec continues to find ways to break down the barriers for simplifying UV spectroscopy and sensing applications. For long-term performance, Optran UV fibers and PowerLightGuide bundles set the standard. Long-term tests of our Optran UV fibers exhibit level, steady transmission at 95% (ë=250nm) of the original input!
