3.5 Working with spectra
In Waves, you can have several spectra loaded at the same time for easy comparison and
analysis. On the upper left side you can see the Spectrum List. Whenever you take a new
spectrum, it appears in this list as “current spectrum” and overwrites any previous
“current spectrum”. If you would like to keep this spectrum and take another one, just
click on the single push pin button [ ]. This prevents the current spectrum from being
overwritten. A new spectrum you take is then appended to the list. Giving the “current
spectrum” a new name also prevents it from being overwritten. You can also choose to
keep all new spectra by selecting the button with multiple push pins [ ] in the Exposure
Toolbar.

When you have multiple spectra in the list, one spectrum is always selected (marked by a
gray bar). All metadata and additional information for this spectrum is displayed in the
Properties Panel on the lower left side. The Properties Panel has five Tab pages:

• General: Displays spectrum metadata. “Name” corresponds to the name in the
Spectrum List. “User” is automatically set to the current Windows user name, but
can be changed. “Sample”, “Light” and “Comments” can be freely edited by the
user. You can change the color of the spectrum by clicking on the color box. Please
note that “User”, “Sample”, “Light” and “Comments” is the same for all spectra in
the list.

note that “User”, “Sample”, “Light” and “Comments” is the same for all spectra in
the list.
• Values: Displays statistical values both for the whole spectrum and within the
selection (if you have selected a range of wavelengths in the diagram).
• Color: Displays colorimetric values. For precise color measurements please also
read the section on calibration accuracy in chapter 3.9.
• Peaks: Displays peak positions, heights and widths. This list can be save to a file by
choosing “Export Peaks” from the file menu.
• Data: Displays a list of all values of the spectrum.
Some of the values in the Properties Panel are saved when saving the spectrum to a file.
The others are recalculated when the spectrum is reloaded.

3.6 File Operations
You can save the selected spectrum or the whole Spectrum List using the commands in
the File menu. You can also open spectrum files to load them back into Waves for further
evaluation (sounds obvious, but surprisingly, many spectroscopy applications don’t even
support this).

evaluation (sounds obvious, but surprisingly, many spectroscopy applications don’t even
support this).
The file format for spectra is a simple ASCII table with columns delimited by the TAB
character and some header lines containing the metadata. This allows the spectrum files
saved by Waves to be read by almost any numerical analysis software like Origin, Excel or
