Hello Optics Team!
I meet a question when writing ZPL. There is a mirror-reflected system and I would like to do the sensitivity analysis on some tolerances. When it comes to decenter, I found that it was difficult to pick up a surface’s ‘Before surface tilt/decenter’. There is a function of picking up ‘After surface tilt/decenter’ (SURP 66) but no such a function for ‘Before surface tilt/decenter’.
Anyone have some experience about it? Thank you!
