WebThe quantum efficiency states that for every photon coming in there’s a probability of X % that the photon will generate an electron that is measured by the detector. If a detector has a quantum efficiency of 60%, and 100 photons are impinging on its surface then the detector will count on average 60 electrons. The remaining 40 are lost. WebT h e superficial conclusion would be that if the visible irradiance is about 50 per cent of that in the open, then a supplement of infra-red increases the weights of the seedlings, the increase being proportional to the intensity of the added infra-red. (Note that the irradiation is measured as the heat content, not as the flux of photons.)
