If Wavelength Certification has passed, the user may click
“Print Report” for hard copy. Otherwise, click on “Close
Report”.
Test results are saved in the Diagnostic Database for
future recall. See the Vision manual for a full explanation.
Wavelength Certification also tests certain 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
wavelength standard. These are the same peaks used during Instrument Calibration. Wavelength
Certification is a verification that the peaks are in correct positions, and that the peak positions are
consistent over time. Note that both tests use the wavelength standard at the sample plane, where
actual sample measurement is done.
