Discovering Photon Flux from UV Source

Click For Summary

Discussion Overview

The discussion revolves around the possibility of determining the photon flux emitted by a UV source using only the intensity and wavelength spectrum of the source. The focus is on the necessary measurements and units required for such a calculation.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the feasibility of calculating photon flux from the intensity and wavelength spectrum of a UV source.
  • Another participant suggests that additional units are necessary for the calculation.
  • A third participant mentions the need for counts per integration time to quantify intensity.
  • A later reply emphasizes that measuring power over the area of exposure is also required, indicating that the initial information is insufficient.

Areas of Agreement / Disagreement

Participants express differing views on the sufficiency of the provided data for calculating photon flux, indicating that the discussion remains unresolved.

Contextual Notes

Limitations include the lack of specific units and the need for additional measurements related to power and area of exposure.

Hi!

I would like to ask if there is possible to find out the photon flux emitted by a uv source having only the intensity/wavelength spectrum of the source?

Not without some units somewhere.
 
Counts/Integration time [13ms here] for the INTENSITY

That still doesn't say anything. It should be measuring power over the area of exposure, the latter is another quantity that you need.
