Fiber Probes for Process Spectroscopy

Fiber probes for process spectroscopy are based on coherent bundle design and provide the best coupling efficiency with spectrometers, light emitters (LED, lasers, lamps, etc.) and media of spectral analysis to investigate its reflectance, fluorescence or absorption spectra.

● Multi-channel process – photometry and spectroscopy with up to 37 channels capacity

● High optical throughput at a pre-selected set of characteristic wavelengths

● Compatibility with a variety of light sources, filter, and mini-spectrometers

● Special design for customer application

● Assembly with polymer or metal coated fibers

● High-temperature probes for up to 600°C applications

● Fiber diameter from 100 µm up to 600 µm in coherent bundles with up to 469 fibers
