I have a suggestion to put a G column in the MFE. This would indicate what surface the operand referred to. Like
REAY S4 W2 G6 Hx Hy Px Py
this would mean that you want the Y ray height on surface two, relative to surface 6. It would do away with the global operands like RAGY, RAGX and so forth. It would allow one to get global values for every operand in the MFE.
Anyone have any thoughts on this? Am I missing something? Seems so obvious to me. But maybe there’s a reason Zemax can’t make this change.
