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

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

Features

• Create SQLite database from refractiveindex yml folder.
• Create SQLite database from refractiveindex.zip url.
• Search database pages by approximate or exact terms.
• Search material data (refractiveindex, extinctioncoefficient) by intervals.
• Execute custom SQL queries on the database.
• Export material data (refractiveindex, extinctioncoefficient) to numpy arrays or csv files.
• Get data (refractiveindex, extinctioncoefficient) at specified wavelengths.

Usage

Just copy the refractivesqlite folder to your project, and you are ready. For more information, see the Tutorial notebook

Dependencies

• python 3
