SUMMARY

The discussion focuses on calculating the number of photons emitted from a xenon-arc lamp using chemical actinometry, specifically employing Potassium Ferrioxalate as the chemical actinometer. Participants emphasize the necessity of identifying specific wavelengths of interest, as it is impractical to cover all wavelengths emitted by the lamp. The conversation highlights the importance of selecting an actinometer that aligns with the desired wavelength range for accurate photon count measurements.

PREREQUISITES
  • Understanding of chemical actinometry
  • Familiarity with Potassium Ferrioxalate as a chemical actinometer
  • Knowledge of photon emission and wavelength measurement
  • Basic principles of light sources, specifically xenon-arc lamps
NEXT STEPS
  • Research the principles of chemical actinometry in detail
  • Learn about the specific wavelength ranges of xenon-arc lamps
  • Explore alternative chemical actinometers for different wavelength applications
  • Study methods for measuring photon emission accurately
USEFUL FOR

Researchers in photochemistry, optical engineers, and anyone involved in the measurement of light emissions from xenon-arc lamps.

Hi all!

Problem.
I have a light source (xenon-arc lamp) and wish to calculate the no. of photons emitted. It seems that I have to use chemical actionmetry (Potassium Ferrioxalate as Chemical Actinometer)? I need to know the no of photons emitted at all wavelengths given out by the lamp at a particular distance. Any ideas?

Hope you can help ;)

It is not possible to cover all wavelengths. You will have figure out what wavelengths you are really interested in and find an actinometer with a similar range or maybe slightly larger.
