make_cauchy_glass

hcipy.optics.make_cauchy_glass(coefficients)

The Cauchy equation for the dispersion of the refractive index of materials.

The dispersion relation of the Cauchy equation is,

\[n = \sum_{i=0}{\frac{K_i}{\lambda^{2i}}\]

Parameters:

coefficientsscalar or array_like

The Cauchy coefficients in um**(2*i).

Returns:

function

The refractive index profile function
