How to calculate uniformity coefficient
WebIn this section, the MATLAB code of thin film calculator is given, as well as an example of the broadband reflector design for the visible region. Two functions multilayer_s.m and multilayer_p.m are built in MATLAB for different polarization incident light, and they are the core program of thin film calculator. They calculate the amplitude WebThus, by using the formula, we can calculate U1 = Minimum / Average lux = 551 / 624 = 0.88, and U2 = Minimum / Maximum lux = 551 / 708 = 0.78. The maximum lighting …
