Fluorescent lights feature strong radiation at certain wavelengths due to the presence of mercury (image on the right):

Is there a way to create a filter that will selectively absorb these spikes, meaning the ones at ~500nm and ~415nm, while allowing energy at other wavelengths to pass through?

Is there a standard resource that tells the absorption spectra for different materials?

  • $\begingroup$ First, why do you need to do so? The application matters for a reasonable answer. $\endgroup$ – Jon Custer Aug 14 '17 at 22:18
  • $\begingroup$ what peak at 500 nm? Do you mean 545nm? $\endgroup$ – jmh Aug 14 '17 at 22:32
  • $\begingroup$ Absorbing the peaks would reduce the energy efficiency making it closer to incandescent. The only remaining advantage of mergury over halogen would be a longer life. $\endgroup$ – safesphere Aug 14 '17 at 22:55
