Wavelength Accuracy - Jasco V-530 Hardware/Function Manual

4.3.3 Wavelength Accuracy

To check wavelength accuracy, measure the spectra of the D
emission line at 656.1 nm and 486.0 nm.
(1) Light only the Deuterium lamp (see item (1) in Section 4.3.2).
(2) Start [Spectrum Measurement] from the [Spectra Manager] window and set
the following parameters.
<<Parameters for spectrum with an emission line at 656.1 nm>>
V-530 measurement parameters
Photometric Mode Sample
Response Fast
Scanning Speed 40 nm/min
Start 658 nm
End 654 nm
Data Pitch 0.1 nm
Display 0~100
No. of Cycles 1
Note: PMT voltage
<<Parameters for spectrum with an emission line 486.0 nm>>

End
All other parameter settings are the same parameters as shown above.
(3) Measure the spectrum of the D
at 486.0 nm with the sample chamber empty. Measurement examples are
shown in Fig. 4.5 and Fig. 4.6.
