Tolerance Monte Carlo
Simulate per-layer thickness and refractive-index variations across thousands of samples to see how your stack design behaves under realistic production tolerances.
Validation: hand-checked example → /validation#tolerance-mc
Wraps the validated Transfer Matrix Method kernel with a Gaussian per-layer perturbation sampler. Outputs mean spectrum + ±1σ / ±2σ bands + worst-case envelope + yield-at-spec.
