Any dataset here, as the library's Tabulated material (schott-borofloat33/schott).

# ... load mat as above, then:

Dispersion formula

Sellmeier (formula 1), λ in µm

n^{2} - 1 = 0.3542 + \frac{0.78657 λ^{2}}{λ^{2} - {0.10856}^{2}} + \frac{0.18285 λ^{2}}{λ^{2} - {4.427}^{2}}

Valid from 0.24 to 1.55 µm.
