Wavelength Scaling
The wavelength units in the opened data file are either not given or given in pixel/points. The data is
displayed as a function of the data points. For scaling the wavelength, two options are available:
 2 Points – Specify the wavelength of two data points in nanometers and click OK.
 Point and dispersion – Specify the wavelength of one data point in nanometers and the
dispersion of the spectral data in nanometers/points and click OK.
If the line cursor is activated in the opened data file, you can take the data points directly from the line
cursor position. Use the following procedure.
► Procedure
To take data points directly from the line cursor position,
1. Move the line cursor to the desired position in the diagram,
2. Set the cursor to the edit box in the dialog box for the selected data point.
3. Click the Get value at line cursor button. The point or pixel number is copied to the edit box.
To skip the unit check while opening a new data file, uncheck the Propose conversion automatically
box. You can convert the wavelength format later using the menu command Edit | Wavelength Format
menu command.
