What is included

Caustiq analyzes beam-width measurements and image sequences, fits X/Y caustics and M² values, and provides 2D spot and 3D point-cloud views. The Test Principle window uses a project-authored schematic and laser-to-detector ray animation. The English manual describes functions, calculation principles, limitations, and the ancillary astigmatism interpretation.

Verification and important limitations

This is a pre-release. Fifteen source regression tests and an offline standalone-EXE self-test passed. The installer is unsigned, and installation/uninstallation has not been validated on a clean Windows machine. If Windows application-control policy blocks it, do not disable or bypass security controls; use an authorized signing/IT process. Hardware calibration, uncertainty analysis and full ISO 11146 compliance have not been established. A complete binary dependency/license audit also remains the maintainer's responsibility; see the attached notices and checklist.
