New function is added to Illuminance spectrometer IM-1000

May 12, 2014

Photosynthetic photon flux density(PPFD) can newly be measured

Illuminance (lx) is common in the measurement of illumination.
But illuminance is related to the sensitivity of typical human eyes,
not sensitivity of vegetable.  
So the illuminance is not appropriate for evaluation of the effect of illumination on vegetable.

PPFD expresses the number of photons in wavelengths the 400-700 nm range of the light that chlorophyll can absorb.
So PPFD is used to evaluate the effect of illumination on photosynthesis in plant factory.
