When we irradiate a 3D-CPC with a parallel beam changing the incidence angle, the reflected beam shows a polar angle with a FWHM constant, why?

When we irradiate a 3D-CPC with a parallel beam, changing the incidence angle (alpha in) but keeping the input flux constant, if the incidence angle is greater than the acceptance angle, all the...
