umol/s ....I believe the spectrum has to be digitized to get this number? It isn't in any datasheet I am aware of...past umol/s for Various chips are posted somewheres....who will chime in...
@alesh...can you explain calculating PPF a little Further?
also
QER will give you PAR watts emitted but joules per umol is how to calculate umol/s.
Calculating PPF
PPF /nm = (10-3) * [λ Φ(λ)] / (Nahc),
where:
Na = Avogadro's constant, 6.022 x1023
h = Planck's constant (6.626 x 10-34 joule-seconds)
c = speed of light, 2.998 x 108 m/s
λ = wavelength in meters.
