Film dispersion (Cauchy)
n(λ) = A + B/λ² + C/λ⁴ with λ in µm. Defaults from refractiveindex.info. Edit to match your ellipsometry / process values, then Design or Apply plots.
HfO₂ (H)
Al-Kuhaili 2004 ↗e-beam HfO₂ film Cauchy on refractiveindex.info. IBS films are often denser (n≈1.95–2.05 @ 1 µm) — edit A/B/C to match your run.
SiO₂ (L)
Malitson 1965 (Cauchy fit) ↗Cauchy fit to Malitson fused silica (VIS–NIR). Substrate uses the exact Sellmeier.
Preview @ 1053 nm: n(HfO₂)=1.8811 · n(SiO₂)=1.4497Substrate fused silica stays Malitson Sellmeier (refractiveindex.info).
