Beamcairn: Laser Optics

Beamcairn: Laser Optics is a focused, fully on-device app. A visual laser-optics bench for Gaussian propagation, ABCD trains, waist placement, cavity stability, diffraction, fiber coupling, and tolerance sweeps. KEY FEATURES - Drag-reorder ABCD optical train - Beam-radius and curvature plot - Cavity stability map - Fiber-coupling tolerance sweep - Lens and glass reference library - Editable complete sample and local project persistence - CSV input plus local PDF and data export - Fifty-two original offline reference plates ONE-TIME AND PRIVATE - One paid download; no subscription or in-app purchase - No account, advertising, analytics, tracking, or developer-operated backend - Core features and bundled content work offline - Work remains on device unless you deliberately share or export it through an Apple system interface Paraxial design aid, not a substitute for full wavefront, coating, damage-threshold or laser-safety analysis.
