I want to understand how the OPDC built-in function in ZEMAX is calculated, and I hope to reproduce the OPDC calculation through ray tracing and programming or other methods.
The focus of the question is the specific operation method. I already know that opdc is the subtraction of the reference sphere and the backward tracking distance.
I would be very grateful if you could answer!
Sincerely，Nancy
