Avantes offers a wide range of fiber-optic cables, which can be manufactured in a variety of lengths and configurations to meet your needs. For common applications, a 2-meter length is sufficient. For this reason, it is our standard fiber length.
Avantes offers SMA-905 or FC/PC connectors and these can be the same or different on both ends. For some applications, special round to linear fiber cables are recommended in which a bundle of fibers configured in a round pattern on one end and a linear array on the other end. The linear array (typically 1mm in height) is aligned with the slit height of the spectrometer which is also 1mm. This fiber configuration provides maximized light throughput for applications requiring high sensitivity.
Fiber-optic cable types and diameters are recommended based on the wavelength range being measured and the sensitivity required for a measurement. In general, different fiber types can be classified. For the UV range, high OH UV/VIS fiber is used. For customers working below 240 nm in the UV, special high OHUV/VIS fibre called solarization resistant fiber (SR) is available. For longer wavelengths low OH VIS/NIR fiber is recommended. Best of both worlds can be achieved without broadband fiber, which is our standard. This gives you the combined performance of the UV, UV-SR and IR fibers.
Depending on the application requirements Avantes offers a variety of jacketing options including Kevlar reinforced PVC sleeving with PTFE inner tubing (Standard), heavy industrial chrome plated brass mono-coil, stainless steel (BX), silicone coated stainless steel mono-coil (MS), flexible chrome-plated brass outer jacket with hooked profile (ME) and other special jacketings upon request. For applications requiring high-temperature resistance, special high-temperature epoxy (HT) is available and should be specified at the time of order.
Recommended wavelengths for different cables:
200-2500 nm: UV/VIS/NIR (UVIR)
UV/IR available in core sizes 100, 200,400, 600 μm
200-800 nm: Solarization-resistant (-SR)
250-800 nm: UV/VIS (UV)
350-2500 nm: VIS/NIR (IR)
