Spectrum
Turn on the device on the home page, press the right button and start measuring the spectral value of the target immediately, the red light on the left side starts to turn off, the device starts to match the test parameters. When sampling is completed, the red light turns on and the spectral graph is displayed, and the color parameters are also output, as shown below in the left figure.
To view the detailed results, press the middle button, which first displays the lower right graph, color rendering index Ra, R1-R15. Press the middle button again to switch to the spectral energy statistics and illuminance, irradiance, and EML EDI values; PPFD is the optical quantum density plot in which this data is 18.571 umol/m^2/S. Blue light irradiance is the result of the convolution of the blue light hazard spectrum weighting function with the spectral energy distribution according to IEC 62471:2006. In order to facilitate the application of the spectrum, the energy distribution percentages of the wavelength interval between UVA and 100 nm are given.
Right click to enter the spectral measurement mode, then press the right button to execute the spectral measurement, view the detailed measurement results by the middle button Left click to exit the spectral mode and return to the main page.
