Step-Index Multimode UV-VIS Optical Fiber for Spectroscopy & Photonics

Description

Progressive absorption of the fibers to the point of complete failure occurs when using UV-VIS fibers < 240 nm. Our solarization- stable fibers can be used for applications in this critical range. These newly developed fibers with high OH content are characterized by very good transmission in the 190–250 nm range. A deuterium light source was used for the measurement.

Advantages of Step-Index Multimode UV-VIS Fibers
Step-index multimode optical fibers are designed with a uniform core refractive index and a distinct refractive index transition between the core and cladding. This architecture supports efficient light collection and high optical throughput, making these fibers particularly suitable for spectroscopy, sensing, UV-VIS analytical instrumentation, and laser delivery systems. Large-core step-index fibers provide improved alignment tolerance and enhanced coupling efficiency for broadband ultraviolet and visible light sources, enabling stable optical transmission in demanding scientific and industrial photonics applications.

Large-Core Fiber Configurations for High Optical Throughput
FiberTech Ultrasol UV-VIS fibers are available in core diameters ranging from 100 µm to 600 µm, supporting efficient optical coupling and high light collection performance across a broad range of spectroscopy, sensing, and laser delivery systems. Larger core diameters improve alignment tolerance and optical throughput, making these fibers particularly effective for ultraviolet and visible light transmission in analytical instrumentation, fluorescence systems, and industrial photonics applications.

Flexible Coating and Jacket Options for Industrial and Scientific Environments
FiberTech Ultrasol UV-VIS fibers are available with polyimide and acrylate coatings to support different thermal, mechanical, and environmental requirements. Optional Nylon® and Tefzel® jackets provide additional protection for industrial, laboratory, and harsh-environment applications requiring improved chemical resistance and long-term durability.
