Hello!
I’m reverse-engineering a system, and have come across some problems.
Why are the rays that are coming from the first surface stopping at the imaginary radius of surface 2 in the below image? The bottom part shows it more clearly.

Hello Oscar,
unfortunately I don’t see the Lens Data Editor. Nevertheless I would say it has got to do with the “Clear Semi-Diamter” vs. “Mechanical Semi-Diameter” settings. Did you apply a certain amount of “Chip-Zone” to the surfaces? How about the vignetting settings shown in Field Data Editor? Have you got “Float-by-Stop-Size” or Image Space F/# defined as aperture of the lens?
Kind regards,
Christian
For me it looks like you set too large EPD (or aperture stop diameter). Try to reduce it.
Christian and Andrey both made a lot of good points. All of the problematic rays are passing outside the clear semi-diameter and moving forward in a non-physical way. The rays are trying to go where their optical path is not well defined, and we’re seeing the points where OS’s best effort to trace them fails.
