From the developer:
OPUS Viewer is a free program that can open all kinds of Bruker's OPUS, JCAMP-DX and Galactic Grams files while data processing and evaluation is not possible. It allows you to display spectral data (spectra, interferograms etc.) as well as other data saved together with the spectrum such as reports with evaluation results, measurement parameters, audit trails, signatures etc.
You may want to check out more software, such as Free Microsoft Project Viewer, Free MSG Viewer or .NET MAUI PDF Viewer, which might be related to Opus Viewer.
