Coherent Multi-Channel Fiber Optic Bundles For Remote Spectroscopy

Coherent multi-channel fiber optic bundles for remote spectroscopy

Round-to-Round (R/R) and Round-to-Line (R/L) fiber bundles are one of the most popular products due to their use in the manufacturing process of a wide range of fiber optic probes and sensors. The fiber R/R and R/L probes come in straight, bifurcated multi-furcated designs.

We offer unique bundles with metal-coated fibers, which blocks the cross-talk between the fibers and results in a higher signal to noise ratio compared to similar bundles with polymer coatings. Such bundles are an excellent choice for spectroscopy.

Our silica fiber bundles are terminated with SMA905, FC/PC, ST or custom connectors and for spectral range from 0.2µm up to 2.2 µm.
