Spectral attenuation of optical fibres
FSL300 from BenthamThe FSL300 system provides accurate assessment of fibre spectral loss, which is of paramount importance in quality control processes, materials research and optical fibre development. Using the internationally recognised reference test method, the cut-back technique, the FSL300 provides high measurement accuracy across all fibre types. Due to the sequential operation of this technique, the FSL300 has excellent optical and mechanical stability and repeatability at the cut-back end to ensure the highest level of measurement reliability.
- Accurate evaluation of the spectral losses by cut-back technique
- Wavelength range across the entire UV-Vis spectrum; Extendable for IR to over 5000 nm
- For a wide range of fibres (i.e. silica, doped glass, plastic and photonic bandgap fibres)
- Light source and launch optics firmly bolted to the monochromator
- No mechanical instability over time
- dB/km Loss calculation as a function of wavelength
Further information
The FSL300 is modular and offers maximum configuration flexibility through independent selection of light source, monochromator, lock-in amplifier, detectors and optics.
Advantages
- Superior optical and mechanical stability
- Modular design and high configuration flexibility
- Simple and reproducible measurement process
- Fully automatic measurement and calculation of spectral attenuation
Displayed parameters
- Spectral attenuation of the fibre, dB/km
