WebMar 1, 2024 · In this work, we generalize the paraxial ray-tracing formulas to include nonparaxial rays. For a refracting (reflecting) spherical surface, a new single meridional formula is derived. This formula can be easily reduced to a paraxial formula. It can also be applied to any aspheric (or general) surface with a known equation. Also, a new exact ray ...

Toric RayTrace - ray missing surface. If a ray cannot intersect with a surface [ignoring apertures], then a flag is set and the ray trace ceases. For toric raytraces, this ‘ray miss’ was properly detected, but the flag was not set, so the raytrace continued spuriously. The flag is now set appropriately. sharex themes
