You have the possibility to use your own calibration data for setting the
wavelength scale of the spectrometer. The calibration dialog can be reached via
the device properties dialog in the tabpage "Calibration". Here you can start the
calibration by pressing "Calibration" button or switch between the factory or the
user calibration data set. SPLICCO will notify you if "User calibration data set" is
selected but not present.
Figure 52 Calibration tabpage
The wavelength calibration window is devided into two parts. The actual
measurement is shown on the left side. You can zoom into the graph by holding
the CTRL key and boxing-in a region of interest or pressing the "Auto Zoom In"
button. It is always possible to zoom to the original window by pressing the "Zoom
home" button or to refresh the graph by pressing the "Refresh" button. The blue
cursor in the graph always snaps to a data point so that you can mark a peak
graphically. The graphically marked point is shown in the "Edit Calibration Points"
box.
A minimum of four and a maximum of ten calibration points are required for a
valid calibration. If you calibrated the instrument beforehand the "Calibration
points" list on the right side of the window is filled with the former calibration
points.
You can edit a calibration point by selecting it in the "Calibration Points" list. The
point can be edited with the controls in the "Edit Calibration Points" box. Press
"Accept" to make the changes valid. To add a new point press "Add" and a new
point will be added to list and can be edited. To delete a selected point press
"Remove" and the point will be removed from list.
