4.3 Wavelength Accuracy Check and Adjustment
Note
: Before checking wavelength accuracy, warm up the instrument for about one
hour after turning the light source ON.
Note
: Use neodymium glass as the sample.
<Procedure>
(1) Start up the Spectrum Measurement program.
(2) Select the [Parameter...] command from the [Measurement] menu, and designate
the measurement parameters shown in Fig. 4.8.
Fig. 4.8 Measurement parameters (wavelength accuracy check)
(3) Mount neodymium glass in the sample chamber.
(4) Select the [Start] command from the [Measurement] menu in order to perform
measurement.
(5) Using the spectrum analysis program, verify that the peak wavelength of Channel
2 (Fig. 4.9) of the measurement data is 586
±
0.8 nm. If the peak wavelength
does not fall within this range, adjust the instrument according to the following
procedure.
