A quantum refers to the minimum quantity of radiation, one photon, involved in physical interactions (e.g., absorption by photosynthetic pigments). In other words, one photon is a single quantum of radiation. Our Full-spectrum Quantum Sensors feature an advanced optical detector that provide high-accuracy PAR measurements (400-700 nm) under all light sources, including all modern colored LEDs. The LI190R Quantum Sensor, manufactured by LI-COR, accurately measures photosynthetic photon flux density (PPFD), which is the number of photons in the 400 to 700 nm waveband incident per unit time on a unit surface. Our Original Quantum Sensors feature a less expensive optical detector that is excellent for measuring broadband light sources, but less accurate when measuring certain LED colors.

The LI190SB-L measures photosynthetically active radiation (PAR), a spectral range of solar radiation from 400 to 700 nm. Photosynthetically active radiation, often abbreviated PAR, designates the spectral range (wave band) of solar radiation from 400 to 700 nanometers that photosynthetic organisms are able to use in the process of photosynthesis.This spectral region corresponds more or less with the range of light visible to the human eye. It measures up to 10,000 μmol/s compared with 2,000 μmol/s for other meters on the market. It uses a silicon photovoltaic detector mounted in a cosine-corrected head.

Skip to main content.sg. 4.7 out of 5 stars 56 Plants utilize this radiation to drive photosynthesis, though individual plant responses to incident radiation may vary within this range. Light Measurement for Human & Animal Studies. This quantum sensor connects directly to our data loggers. Photosynthetically Active Radiation or PAR light lies in the range 400-700nm and is the part of the sun’s spectrum used by plants for photosynthesis. This PAR meter can measure PAR up to 10,000umol/s which is more than enough in testing for proper PAR. Measure the the voltage across the sensor, divide that by 0.604 to get millivolts, divide that by the calibration value to getmillimoles per second per square meter. Spectral Range340 to 1040 nm ± 5 nm (wavelengths where response is greater than 50 % of maximum). Light SourceExcellent for all light sources except certain colored LEDs, although post-measurement correction factors can be applied to improve accuracy. A quantum sensor measures photosynthetically active radiation (PAR, in μmol of photons m-2 s-1) in the 400 nm to 700 nm waveband. There is a proportional relationship between the number of photons absorbed in 400 to 700 nm band and the rate of photosynthesis in plants. Spectral Range400 to 700 nm ± 5 nm (wavelengths where response is greater than 50 % of maximum). PAR Line Quantum Sensor Photosynthetically Active Radiation or PAR light lies in the range 400-700nm and is the part of the sun’s spectrum used by plants for photosynthesis. Description.
