9. Click to apply the file data to your graph on the main SpectraSuite screen.
10. To permanently save the spectrum to disk, click the Save Spectra ( ) icon on the toolbar.
Note
If you change any sampling variable (integration time, averaging, smoothing, angle,
temperature, fiber size, etc.), you must store a new reference and dark spectrum.
Irradiance Experiments
Irradiance is the amount of energy at each wavelength emitted from a radiant sample. Absolute irradiance
is the measure of light in absolute terms. Relative irradiance is a comparison of the fraction of energy the
sample emits and the energy the sampling system collects from a lamp with a blackbody energy
distribution (normalized to 1 at the energy maximum). SpectraSuite calculates relative irradiance with the
following equation:
