It is computed and plotted in your browser by a Java program which reads a file containing a list of emission line wavelengths and their corresponding strenghts.
Note: This program generates deep 24 bit color plots, therefore you may need to increase the color depth of your system to view subtle details in these spectra.
There may be a small delay as each Applet loads its element emission line file and computes the spectra...

and from 5500 to 7000 Ångstroms
