Read Spectroscopic Data from Bruker OPUS Binary Files // Reads data from Bruker OPUS binary files of Fourier-Transform infrared spectrometers of the company Bruker Optics GmbH Co. This package is released independently from Bruker, and Bruker and OPUS are registered trademarks of Bruker Optics GmbH Co. KG. https://www.bruker.com/en/products-and-solutions/infrared- and-raman/opus-spectroscopy-software/latest-release.html. It lets you import both measurement data and parameters from OPUS files. The main method is `read_opus()`, which reads one or multiple OPUS files into a standardized list class. Behind the scenes, the reader parses the file header for assigning spectral blocks and reading binary data from the respective byte positions, using a reverse engineering approach. Infrared spectroscopy combined with chemometrics and machine learning is an established method to scale up chemical diagnostics in various industries and scientific fields.
