Dear all,
I just obtained the grid sag surface from the NSC analysis, and I would like to convert it to a freeform surface expressed by extended polynomials. I try to do the surface fitting on Matlab, but the precision is unsatisfactory. So, is there any internal method in zemax can help me to achieve the conversion? Or is there any good algorithm that improves the precision of the 2D surface fitting?
Thanks in advance
Daoming
