UV-VIS Optical Fiber

UV-Vis optical fibers are specialized optical fibers, it is designed to efficiently transmit light within the ultraviolet to visible wavelength range, Usually it have a range from 200 nm to 1150 nm which makes them essential components in UV-Vis spectroscopy and related analytical applications. These fibers usually use fused silica core surrounded by a cladding material with a lower refractive index, that enable light confinement through total internal reflection. The key parameters to identify the best UV-Vis optical fiber include high transmission efficiency, especially for deep UV wavelengths to ensure minimal attenuation, it is often less than 1 dB/m at 200 nm, a suitable core diameter ranging from 50 µm to 1000 µm that match to the application and an appropriate numerical aperture for example 0.22 or 0.37 to optimize light collection and delivery. The durability in environmental stress such as a temperature variation from -65°C up to +300°C and resistance of UV solarization are also critical. While protective coating like acrylate, polyimide or Tefzel enhance fiber longevity and mechanical stability. The spectral performance must be consistent to maintain signal stability and low noise in spectroscopy or sensor system. The chemical analysis, polymer additive monitoring and precise spectroscopic measurements, where coupling UV-Vis fiber to spectrometers or probes enables remote and safe sampling. It is important to meet the standard such as DIN 58145:2017-01 which ensures reliable solarization resistance and optimal signal to noise ratio, it is usually under 220 nm. These factors play important role in selection of UV-Vis Optical Fiber to meet analytical and industrial requirements. Now you can find out optical properties of the product we are selling below.
