I have surfaces near the focus of an aberrated system and I’m seeing that the Clear Semi-Diameter is being automatically set much smaller than the actual beam size. I know that this is because the surface is in a caustic region and I can set a fixed value rather than leave it as automatic. I’d like to have another option, to size it based on something other than the marginal ray height at the surface. What options do I have?
