Fiber Probes for Process Spectroscopy

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