The first tab shows the Wavelength positions, as found. They are compared to the NIST nominal peak
positions, or the empirically-determined positions for talc peaks. The difference from nominal, and
the repeatability of position are calculated.
Wavelength Certification also tests certain “measured instrument profile” peaks in the wavelength
standard. These peaks are used to set the “Instrument Wavelength Profile,” and one peak is used for
bandwidth calculation.
The wavelengths used for the instrument wavelength profile are well-defined, stable peaks in the
