Hello,

There is no easy answer to measure photons, but using a radiometric/spectral sensor, you can obtain a value in watts, then from this, knowing time you can find energy and then calculate the number of photons from the energy of a single of photon at a known wavelenght. 

You can find help to setup a measure in the result at this adress : Making Measures Analysis
