Hi
I am trying an off-axial mirror in sequential mode.(pic1)
I refers to the KB here(a little )
https://support.zemax.com/hc/en-us/articles/1500005486541-How-to-model-an-off-axis-parabolic-mirror
but met this problem , the mirror tilted, when I added hard aperture to it.(pic2→pic3)
I attached the data ,and could you give me some hint?
thank you
