riip 0.1.0

Python 3 + Pandas wrapper for the refractiveindex.info database

RII_Pandas (refractiveindex.info-pandas)

Python 3 + Pandas wrapper for the refractiveindex.info database developed by Mikhail Polyanskiy.

Pandas DataFrame creation was made with modified versions of dboperations.py from refractiveindex.info-sqlite package developed by Hugo Guillén.

Features

• Create Pandas DataFrame by parsing database files cloned from Polyanskiy's GitHub repository.
• Drude-Lorentz model (formula 21) and Brendel-Bormann model (formula 22) are available to describe metallic dielectric function.

Install

Install and update using pip

$ pip install -U riip

Usage

>>> import riip
>>> ri = riip.RiiDataFrame()

Polyanskiy's 'refractiveindex.info database' is cloned from GitHub repository, and three csv files, 'catalog.csv', 'raw_data.csv' and 'grid_data.csv' are created. They are located in 'data' folder under the installation directory. This process may take a few minutes, but it will happen only the first time you start it after installation.

>>> ri.catalog.loc[:30, ['book', 'page']]
>>> ri.raw_data.loc[ri.raw_data['id']==10, ['wl_n', 'n']]
>>> ri.raw_data.loc[ri.raw_data['id']==10, ['wl_k', 'k']]
>>> ri.grid_data.loc[ri.grid_data['id']==10, ['wl', 'n', 'k']]

For more information, see the examples notebook.

>>> ri = riip.RiiDataFrame()
>>> ri.update_db()
