Sources & model notes

The external design is inspired by HEINE BETA 200 LED. It is an educational interpretation, not manufacturer CAD. Internal geometry, exact dimensions and sleeve calibration remain illustrative.

The patient view reuses the existing clinical engine for spherical, plane-mirror teaching cases. Its pupil overlay is illustrative and does not grade clinical performance.
