refind.n_coatings(wl, type='MgF2_o')

Refractive index of common materials used for optical coatings. Data taken from refractiveindex.info.

New in version 10-28-2015: Added indices for rutile TiO2.

Parameters:

• wl (array) – Wavelength axis in um.
• type (str) – Type of coating (‘MgF2_o’, ‘MgF2_e’, ‘ZnSe’, ‘TiO2_o’, ‘TiO2_e’).

Returns:

Rerfractive index (same shape as wl).
