    Count Lamp Photon
Click For Summary
To calculate the number of photons emitted by a xenon-arc lamp, a chemical actinometer like Potassium Ferrioxalate can be used. It's important to focus on specific wavelengths of interest, as it's not feasible to cover all wavelengths emitted by the lamp. Selecting an actinometer that matches or slightly exceeds the desired wavelength range is crucial for accurate measurements. The discussion emphasizes the need for targeted wavelength selection to effectively utilize actinometry. Properly identifying the relevant wavelengths will enhance the accuracy of photon count calculations.

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.
