Optical Fibers

Fiber 8-1000 µm; Standard Length 2 or 1 m; SMA terminators

Avantes provides a diverse selection of fiber-optic cables, available in various lengths and configurations to suit your specific needs.

Fiber-Optic Cables

Avantes offers a wide range of fiber-optic cables, which can be manufactured in different lengths and configurations to meet your requirements. For most applications, a 2-meter length is sufficient, making it our standard fiber length.

Avantes provides SMA-905 or FC/PC connectors, which can be the same or different on both ends. For certain applications, special round-to-linear fiber cables are recommended. These cables have a bundle of fibers arranged in a round pattern on one end and a linear array on the other. The linear array (typically 1mm in height) aligns with the spectrometer slit height, also 1mm, maximizing light throughput for high-sensitivity applications. Fiber-optic cable types and diameters are recommended based on the wavelength range and sensitivity required for a measurement. Generally, different fiber types are classified as follows: for the UV range, high OH UV/VIS fiber is used. For measurements below 240 nm in the UV, special high OH UV/VIS fiber called solarization-resistant fiber (SR) is available. For longer wavelengths, low OH VIS/NIR fiber is recommended. Our standard broadband fiber combines the performance of UV, UV-SR, and IR fibers, offering the best of both worlds.

Depending on application requirements, Avantes offers various 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 high-temperature applications, 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)

Multi-Furcated Fiber-Optic Cables

For simultaneous multi-point measurements and use with Avantes multi-channel spectrometers, multi-furcated fiber-optic cables are essential. These assemblies can function as either a combiner or splitter of light, featuring multiple legs on one side that converge into a single connector on the opposite side. Avantes offers virtually any combination possible, tailored to meet your specific requirements.

Typical setups that require multi-furcated cables are:

Various types of connectors, jacketings, and fibre sizes are available for these multi-furcated fiber cables. Contact us to configure and quote you on your specific needs.
