Applications of High-OH All-Silica Fiber with Fluorine-Doped Cladding (Optran® UV / Optran® UVNS)

• UV and Deep-UV Spectroscopy – High-OH core and low attenuation from 190–220 nm upward make these fibers ideal for UV and deep-UV absorption, emission, and transmission spectroscopy in research and industrial systems.
• Analytical and Process Instrumentation – Used as flexible light guides in benchtop and inline analyzers for chemistry, environmental monitoring, and process control where stable UV/visible transmission is critical.
• Fluorescence Excitation and Detection – Efficient delivery of excitation light and collection of weak fluorescence signals across the UV–visible spectrum for bioanalytical, diagnostic, and life-science instruments.
• Medical and Biomedical Instrumentation – Integration into endoscopes, catheters, and diagnostic probes for illumination, UV-based diagnostics, fluorescence-guided imaging, and phototherapy where long-term UV stability is required.
• UV Curing and Photopolymerization – Transmission of high-intensity UV for spot curing of adhesives, inks, coatings, and dental materials, with UVNS fibers providing enhanced resistance to solarization under prolonged UV exposure.
• Laser Delivery in the UV–Visible Range – Fiber delivery of UV and visible lasers for micromachining, marking, lithography alignment, and precision illumination where consistent beam quality and low attenuation are important.
• Industrial Measurement and Quality Control – Optical fibers for UV-based inspection, color measurement, gloss and surface analysis, and non-contact thickness or coating monitoring on production lines.
• Environmental and Chemical Sensing – UV transmission for optical sensing of pollutants, ozone, NOx, SOx, organics, and other analytes in water, air, and industrial effluents using fiber-coupled spectrometers and probes.
• Laboratory and Research Applications – General-purpose UV/visible light delivery and collection in spectroscopy benches, optical setups, pump–probe experiments, and photochemistry/photophysics studies.
• Pharmaceutical and Biotech Analytics – Integration in HPLC, UHPLC, CE, and flow-cell based detectors where precise UV absorption and fluorescence measurements are required in compact, modular systems.
• Solar, Photovoltaic, and Material Characterization – Guided UV/visible illumination for characterization of solar cells, LEDs, phosphors, and optical coatings, including accelerated aging tests under intense UV.
• Forensic and Security Illumination – UV and visible fiber illumination for detection of security markings, latent fingerprints, biological traces, and fluorescence tags in forensic and anti-counterfeiting tools.
• UV Imaging and Inspection Systems – Coupling of UV sources to cameras, microscopes, and imaging optics for high-contrast inspection of microstructures, semiconductors, and precision components.
• Microscopy and Bioimaging – Delivery of excitation light in fluorescence microscopy, confocal systems, and flow cytometry, leveraging stable UV transmission for short-wavelength fluorophores.
