Once Vision has finished with this screen, a
result screen will be displayed.
The NIR wavelength positions of
these peaks appear as shown.
The scale of this display is marked
in encoder pulses, which do not
relate to nanometers directly.
From the peaks, a linearization is
performed, which allows
assignment of nanometer values.
The “visible” portion of the
spectrum is similar. A linearization
is applied to this portion of the
spectrum.
Minor artifacts appear in these
raw spectra due to detector
crossover and other spectroscopic
reasons. After linearization these
artifacts are minimal or not
evident, some being beyond the
usable range of the instrument.
