Despite the thing dating back to 1994 it is fully working and can detect down to below 1000 photons per second. Here you find [[File:Berthold_Lumat_LB9501_manual.pdf|thumb]the Manual] with lot's on interesting information on photon counting. The "Relative Light Unit" (RLU) represents 1/10 of the photons detected by the photon multiplier. And RLU factor 390nm - 620nm Quantum-Efficiency of typ 24% at 420nm
