Easy Python interface to RefractiveIndex database

The original database is here https://github.com/polyanskiy/refractiveindex.info-database

Database files parsing was made with a modified version of refractiveIndex.py from PyTMM project by Pavel Dmitriev.

Installation

pip install refractiveindex

Usage

from refractiveindex import RefractiveIndexMaterial

SiO = RefractiveIndexMaterial(shelf='main', book='SiO', page='Hass')

wavelength_nm = 600  # [nm]

SiO.get_epsilon(wavelength_nm)
# (3.8633404437869827+0.003931076923076923j)

SiO.get_refractive_index(wavelength_nm)
# (1.96553846)

SiO.get_extinction_coefficient(wavelength_nm)
# (0.001)

Note: here the time dependence is assumed to be $\mathrm{e}^{-\mathrm{i} \omega t}$, so $\operatorname{Im}\varepsilon > 0$ is responsible for the losses.

How to get material page names

You can find the proper “page” name by hovering your cursor on the link in the Data section

Or you can look up folders in this repository
