Solarization-Stable UV Optical Fiber for 190–250 nm Applications

Description

Introducing our state-of-the-art solarization-stable fibers, expertly designed to deliver exceptional performance in the critical UV-VIS range. These fibers are meticulously crafted with a high OH content, ensuring remarkable transmission capabilities between 190 nm and 250 nm. This makes them an ideal choice for applications requiring precise optical clarity and stability under challenging conditions.

Why Solarization-Stable Fibers Matter

Solarization is a degradation process that occurs in conventional UV optical fibers when prolonged ultraviolet exposure causes defect formation within the silica structure, resulting in increased optical absorption and reduced transmission efficiency. FiberTech Ultrasol fibers are specifically engineered to resist solarization effects in the critical 190–250 nm ultraviolet range through the use of high OH fused silica and optimized fiber manufacturing techniques. This enables stable long-term UV transmission performance in demanding photonics, spectroscopy, and analytical instrumentation applications where conventional UV fibers may experience premature degradation or failure.

Advantages of Multimode UV Fibers in Scientific and Industrial Systems

Multimode UV optical fibers are widely used in spectroscopy, analytical instrumentation, and industrial photonics systems because their larger core diameters support efficient optical coupling and high ultraviolet power throughput. Compared to single-mode UV fibers, multimode fibers provide improved alignment tolerance and enhanced light collection efficiency, making them ideal for deuterium lamp systems, fluorescence measurements, UV curing equipment, and broadband UV-VIS optical instrumentation.

Our fibers are constructed with a fused silica glass core and a fused silica cladding, providing robust durability and reliable performance. The ultrasol® fibers are engineered to withstand the progressive absorption commonly seen in UV-VIS fibers below 240 nm, thereby preventing premature failure and extending their operational lifespan. This innovation is particularly beneficial for applications involving prolonged exposure to deuterium light sources, where maintaining optimal transmission is crucial.

For added versatility, these fibers are available with either single acrylate or polyimide coatings, each offering distinct advantages depending on your specific needs. The option to include coatings such as Nylon® or Tefzel® further enhances their adaptability, allowing them to meet a wide range of environmental and operational requirements. Additionally, these fibers can be configured as fiber bundles with single-fiber cores starting from 30 μm, offering even greater flexibility for complex optical systems.

Choose our solarization-stable fibers for your next project and experience the superior performance and reliability that only advanced optical technology can provide. Whether for research, industrial, or specialized applications, these fibers are engineered to deliver unparalleled results.
