Compare the Refractive Index of BK7 and Fused Silica
====================================================

This example compares two common optical glasses available in
:class:`~PyOptik.material_bank.MaterialBank`. It computes and plots the
refractive index of BK7 and fused silica over the visible to near
infrared wavelength range.
