Tools for non-sequential ray tracing through segmented telescopes for Habitable Worlds Observatory

Architectures are currently being explored for NASA’s upcoming flagship mission, Habitable Worlds Observatory (HWO). Similar to James Webb Space Telescope, the primary mirrors are being designed as segmented rather than monolithic. This introduces the need for non-sequential ray tracing in an optical model. In order to make this conversion process more efficient, a series of macros can be written in CODE V. The programs will turn surfaces from sequential to non-sequential, insert the appropriate number of segments, and automatically generate the required geometries for each part. Considerations include: • Segment shape • Gap size between segments • Segment numbers & orientation composing the full mirror
