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. Thanks to a multitude of accessories, which hook up to the spectrometers as plug and play tools, measurements can be done in transmission, reflection, or absorption. Also, fluorescence and irradiance measurements are possible.
