The noise increases considerably above 12.000 cm

and the baseline is less stable.
These limitations are caused by physics and they are not specific for the NIRFlex N-500 but can be
observed for every FT-NIR spectrometer regardless of the manufacturer.
WARNING
Spectra recorded in the extended range will have a different number of datapoints than spectra measured
in the default range. Mixing up these types of spectra in the same database can cause problems. Please
consider: only spectra measured with the same wave number range are compatible.
There is no way to use both types of spectra in one NIRCal calibration. NIRCal will reject incompatible
spectra from import. If the wave range is not matching, the Spectra Converter can help (see NIRCal
Manual).
Problems may occur using the Library Designer. Mixing spectra with different number of
datapoints is not prevented by design and can cause the software to crash.
Applications configured for a certain wavelength range will crash if a calibration is assigned that
have been developed with spectra of a different wavelength range.
