For the specification of awavelength-dependentrefractive indexof a transparentoptical material(e.g. anoptical glass), it is common to use a so-calledSellmeier formula[1](also calledSellmeier equationorSellmeier dispersion formula, after Wolfgang von Sellmeier). This is typically of the form n(λ)...
