Hi All,

I am modeling optical system where there is a need to know the angles of the propgating rays after reflection, diffraction etc.

However, when using the Detector viewer/radiance space, I found different angles than anticipated.

For example, propagating free rays with tilt x 30, tilt y 20- I got: 21, 28.8 at the detector(attached here):

What happend?

Thanks,

Nadav
