Hello,
I am setting up a system with a diverging source (object space NA), a fold mirror, and then an OAP to collimate the light. In order to collimate the light, the radius on the OAP had to be positive, though I expected it to be negative, which I assume is due to the coordinate breaks and reference position. My question is if I want to model an OAP in this system, is the conic constant still -1 or is it +1?
Thank you,
Dan

For an OAP the conic constant should always be -1 so that the surface is parabolic (surface sag proportional to r^2):
Here’s an example:
