发帖数: 522 | 2 I take it that flux is the number of photons per unit time. (some people use
dkifferent definitions). if the photns are single wavelength, then power
divided by (h time frequency) is the flux. if photons are multiwavelengths,
then you need to know spectrum, it is more complicated, you probably need
measure power for each narrow wavelength window
