Optical constants for elements and various materials in the EUV and VUV wavelengths.
Welcome! This is ocdb, a Python package for easily accessing the X-ray/EUV/VUV scattering and absorption data contained in the Optical Constants Database (OCDB) provided by the German National Metrology Institute, the Physikalisch-Technische Bundesanstalt, PTB.
A list of (planned) features:
- Access to X-ray/EUV/VUV scattering and absorption coefficients (n and k)
- Interface compatible to the periodictable Python package
- Provides data and uncertainties
- FAIR and linked data: citable, reliable, and reproducible
- Offline access: data contained in package
- Community-driven: easy to contribute
And to make it even more convenient for users and future-proof:
- Open source project written in Python (>= 3.9)
- Developed fully test-driven
- Extensive user and API documentation
To install the ocdb package on your computer (sensibly within a Python virtual environment), open a terminal (activate your virtual environment), and type in the following:
pip install ocdb
