Fiber Optic Reflection Probes

Bifurcated reflection probes are designed for reflection and backscatter measurements, combining three fiber legs in one assembly. One leg connects to the light source (SMA905 or FC/PC), the second to the sample (SMA, FC, or custom probe), and the third to the spectrometer. The spectrometer leg can be arranged in a linear structure or circular bundle, terminated with SMA905 or FC/PC connectors.

Core sizes range from 50 µm to 1000 µm, with multimode fibers (Low OH, High OH) and solarization-resistant fibers for UV applications. Mechanical protection includes flexible stainless steel tubing, PVC, or PTFE for durability. End faces can be ARC-coated to minimize back reflections. Lengths are fully customizable to meet application requirements.
