SpectralBench
Read OPUS files anywhere — no Bruker license, no Windows workstation, no vendor lock-in
Vendor lock-in. OPUS only works with Bruker instruments — licenses are tied to specific serial numbers. If your lab uses spectrometers from multiple vendors, you need completely separate software ecosystems. SpectralBench is vendor-neutral and reads data from any manufacturer.
Proprietary file format. OPUS uses a proprietary binary format that can only be read by Bruker software. SpectralBench reads OPUS files natively, freeing your data from the Bruker ecosystem.
Expensive libraries. Bruker sells reference spectral libraries separately at $1,000+ each. SpectralBench includes 50,000+ reference spectra from open databases at no cost.
No collaboration. OPUS has no sharing or collaboration features. SpectralBench lets you share spectra via a single link, contribute to a community library, and generate PDF reports for publications.

No download, no installation, no Bruker license. Just open your browser and go.
Drag your OPUS (.0-.9), JCAMP-DX, SPC, or CSV file onto the viewer. Format is auto-detected.
Identify peaks, correct baselines, run PCA, match references, and export in any format.
SpectralBench reads Bruker OPUS files natively — no conversion or Bruker software needed. Simply drag your .0, .1, .2 (etc.) files directly into the viewer.
Additional vendor-specific formats are on the roadmap. If you need a specific format, let us know.
OPUS is Bruker's proprietary spectroscopy software for their FTIR, Raman, and NIR instruments. It is the primary data acquisition and analysis tool for Bruker spectrometers, but requires a Bruker instrument license to operate.
No. OPUS licenses are tied to Bruker instrument serial numbers — you cannot install or use OPUS without owning a Bruker spectrometer. SpectralBench reads OPUS files without any Bruker hardware or license.
Yes. SpectralBench reads OPUS files (.0 through .9 extensions) natively. Simply drag and drop your OPUS file into the viewer — no conversion or Bruker software needed.
No. OPUS is bundled with Bruker instruments and requires an active license tied to the instrument serial number. There is no free or standalone version. SpectralBench is completely free with no license requirements.
Bruker sells reference spectral libraries separately, typically costing $1,000 or more per library. SpectralBench includes 50,000+ reference spectra from open databases (ROD, NIST, and curated sources) at no cost.
