Line Brightness to Display: NormalBrighterBrightest Wavelength Range to Display: Visible RangeExtended Range On the extended range, purple below 400 nm and white above 750 nm stand in for the colors we cannot see. You can drop a file on the spectra to display data as long as it is a CSV with the format: Wavelength,Intensity. The wavelength needs to be in nanometers and can be an integer or decimal. The intensity should be an integer ranging from 0 to 255.
