【Abstract】 The combination of total spectral radiance factors and the radiance characteristics of fluorescent materials is described. The one monochrometor method and two monochrometor method for measuring fluorescent samples are compared. Furthermore, it discusses in detail how: inncluding the geomety of measurement system, the standard lluminant and the reference standard affect the accuracy of the spectral measurement.更多还原
