High Pressure Sodium spectrum

High Pressure Sodium spectrum

Another difficult spectrum to obtain, as the yellow-orange overpowers everything else. With known lines marked. Bottom strip is that of clear mercury vapor for comparison. HPS is seriously lacking any violet or UV light.

Nice comparison and clarity! I've only used those cheap 5 dollar spectroscopes and noticed the yellow band in mercury vapor resembled a sodium band color. I never really looked to see the exact wavelength comparison but here one can see they are pretty close. It's interesting that different elements can make similar wavelengths sometimes.

And the visible part of the spectrum is only a part of the story. Plus, just started recording the spectra of FAR more interesting lamps, like HPI-T, HQI & ceramic metal halide lamps! See here!
