Available devices and Specifications
The Ocean Optics NIRQuest NIR spectrometers and QE65000 spectrometer are usually installed simultaneously. The fibre optics sensors are installed at the cabin roof looking upward or in the floor compartment looking downward. The are connected to the spectrometers by fibre optics cables. Data aquisition is controlled by an operator PC installed in a rack. A DC/DC converter also installed in a rack provides the required voltage of 5 VDC for the spectrometers.
