Fully meet CIE 177, CIE-13.3, Optical-Engineering-49-3-033602, and IEEE.is the size in microns that splits the distribution with half above and half below this diameter. The Dv50 (or Dv0.5) is the median for a volume distribution, Dn50 is used for number distributions, and Ds50 is used for surface distributions. Since the primary result from laser diffraction is a volume distribution, the default D50 cited The light distribution in the plant canopy under natural light follows the Beer-Lambert equation (Gholz et al. 1991; James et al. 1995). Plant photosynthesis and transpiration can be estimated . Linshang LS116 light transmittance tester is a professional instrument for testing the light transmittance of uniform light-transmitting materials. It uses a parallel light path design and can also be used to detect large thickness materials with an accuracy of ± 1%. Function standard to ensure the passing of testing by the Metrology Institute.
The transmittance calibration set-up has three parts: (1) the source (upper left corner), which in this case is a laser-driven light source that produces UV light; (2) the monochromator, which uses gratings and mirrors to let researchers select a particular wavelength; and (3) the detectors that allow researchers to determine how much light .
