Light intensity of UV component from a xenon lamp

Click For Summary
SUMMARY

The discussion focuses on the UV component emitted by a 100-watt xenon lamp, which constitutes 5-6% of the total spectral output. Participants question whether the entire 100 watts is emitted uniformly across the spectrum or if the power is distributed variably among different wavelengths. The complexity of calculating the UV light power is emphasized, particularly due to the challenges posed by quantum mechanics and the resonances in ionized xenon. A warning is issued to disregard references to Planck distribution or black body curves, as they may not apply to this specific scenario.

PREREQUISITES
  • Understanding of xenon lamp operation and spectral output
  • Basic knowledge of quantum mechanics and energy distribution
  • Familiarity with light wavelength and intensity concepts
  • Awareness of plasma physics and ionized gases
NEXT STEPS
  • Research the spectral output characteristics of xenon lamps
  • Explore quantum mechanics principles related to energy levels in gases
  • Investigate methods for measuring UV light intensity from lamps
  • Learn about the implications of resonances in ionized gases
USEFUL FOR

Physicists, optical engineers, and anyone involved in the design or application of xenon lamps, particularly in contexts requiring precise UV light measurements.

I have a 100watt xenon lamp , the UV component comprises of 5-6% of the total spectrum emitted by the xenon lamp . How do I calculate at what power is the UV light emitted ?

Is the whole spectrum being emitted at 100 W or is the power distributed through the spectrum? How is this distribution of power related to the wavelength of light if latter is the case ?

Sorry this is not an answer more of a warning if you get replies talking about the Planck distribution or black body curve please ignore them.

The distribution of energy between the different wavelengths in ionised xenon is a near impossible problem in quantum mechanics because of the many 'resonances' ie energy level differences the xenon plasma has.

for a picture of what you have see http://astro.u-strasbg.fr/~koppen/discharge/xenon.html

I know this is not of much help but fundamental physics has its limits - that's why its fun
