The IFS 125/HR and the new IFS 125/M mobile spectrometers are the ultimate instruments for the high resolution spectroscopy Outstanding results in your laboratory In absorption or emission mode, the IFS 125/HR can resolve highly complex spectra into discrete lines for recognition and spectral assignment. Outstanding resolution across the entire spectrum Resolved linewidths of 50,000cm-1 in the UV Double-sided interferogram acquisition (option) Symmetric line shapes - due to high precision optics Easy range change - every experiment can access different sources and detectors without breaking vacuum. A total of 4 sources and 6 detectors can be accessed through each of two different sample compartments Glide-bearing interferometer with hybrid scanner construction for enhanced velocity stability
