How to measure PPFD of plant light with spectroradiometer integrating sphere system?

Image
In the field of horticulture, the term "photosynthetic photon flux density" (abbreviated as "PPFD") refers to a unit of measurement that is used to characterize the quantity of photosynthetically active radiation (PAR) that is received by a plant. The part of the electromagnetic spectrum known as the photoactive absorption region (PAR) that plants employ for photosynthesis may vary in wavelength from 400 to 700 nanometers. The photon flux density (PPFD) is measured in mol m-2 second-1, where each mol m-2 second-1 indicates the quantity of photons in the PAR range that strike a certain region in a given amount of time. The light intensity of a grow lamp, which is an essential component in the growth and maturation of plants, may be determined with the use of this measurement. A higher PPFD value implies a greater light intensity and a more suitable growth environment for plants, as long as other parameters, such as temperature and humidity, are also within the i

LED color test with an integrating sphere system
