Absorption in fibers is low enough to transport light through fibers from a process to a far away miniature spectrometer.
Advanced software interprets the measured spectra and calculates specific process parameters.
All this happens so fast that one can speak of true on-line measurements, while the price is only a small fraction of the typical instruments used for this purpose. Several platforms are available. The AVS-S2000 has a 2048 pixel CCD array and is packaged as a small benchtop unit with analog output. All these configurations can be expanded with up to 7 slave units to turn them into true multiple beam spectrometers. All instruments can easily be configured for UV, VIS, or NIR applications in many industries and sciences.
