Hello everyone,
Thank you for your help.What I want is matching POV-Ray output with some
physical measurements.I have used spectral
render.http://www.lilysoft.org/CGI/SR/Spectral%20Render.htm.

#version 3.7;
global_settings{ assumed_gamma 1.0 }
#declare SpectralWavelength =730;
#include "spectral.inc"


light_source {<sun_x,sun_y,sun_z>
             SpectralEmission(E_D65)   //some CIE standard illuminants
             }

My solar irradiance in 730nm is 1.33015(w/m^2),and I have converted irradiance
to illuminance with the lm/w in 730nm,then the value of illuminance in 730nm is
0.47262925(cd/m^2).My issue is how can I input the illminance in 730nm?
"light_source {<sun_x,sun_y,sun_z>
             SpectralEmission(E_D65)
             }  "
With this light_source,the illuminance is E_D65.How can I input my
illminance?Beg you give a help!Expecting your reply!
