Simple ray tracing library in Python for optical design that considers simple optical elements (with ABCD ray matrices) but also finite diameters of elements to calculate aperture and field stops, field of view, etc... Useful to validate the design of an optical system (lenses positions, power and diameters). Also permits the propagation of gaussian laser beams through the same elements.

Stars, PRs, issues and forks are under-captured in the later part of this window. GH Archive progressively stopped capturing non-push events during 2026 — −95% or worse by the end of the window. Every series here except Pushes fades for that reason, so a decline above reflects the archive, not this repository. Pushes stay reliable throughout, so read them, and the contributor counts derived from them, as the real signal. Data health has the measurements.

Totals cover only the window loaded into ClickHouse and count events, not GitHub's lifetime totals — 30 stars here means stars gained during the window, not the repo's star count.
