SpectralBench
Free OMNIC alternative — view SPC files in your browser
Thermo Fisher Scientific instruments — including the Nicolet iS series, Nicolet Summit, and Evolution UV-Vis spectrometers — produce data in SPC format, a proprietary binary format originally developed by Galactic Industries for the GRAMS software suite.
To view these files, you typically need OMNIC or OMNIC Paradigm software. OMNIC requires a physical connection to Thermo hardware or a license dongle. The newer OMNIC Paradigm uploads your spectral data to Thermo's cloud servers — a non-starter for proprietary or pre-publication data. If you've left the lab or moved to a different institution, accessing your own data becomes unnecessarily difficult.
SpectralBench reads SPC binary files directly in your browser — no OMNIC, no hardware dongle, no cloud upload. Drop your .spc file onto the viewer and see your spectrum in seconds with interactive controls.
Need the data in a different format? Export to CSV for Excel, JCAMP-DX for open-standard archiving, or JSON for programmatic access. All processing is client-side — your data stays on your machine.
Note on SPA/SPG files: Thermo Fisher's newer OMNIC Paradigm uses the SPA (single spectrum) and SPG (spectrum group) formats. Native SPA/SPG parsing is on our roadmap. For now, export your SPA data as SPC or CSV from OMNIC, then open it in SpectralBench.
Drag your .spc file onto SpectralBench. The parser handles both old and new SPC format variants.
Your spectrum renders as an interactive chart. Zoom in, detect peaks, and inspect metadata from the SPC header.
Convert to CSV, JCAMP-DX, JSON, or MATLAB. Download instantly — no server round-trip.
SpectralBench isn't limited to Thermo Fisher files. Open spectral data from any instrument:
Yes. SpectralBench reads SPC files — the binary format used by Thermo Fisher (Nicolet) instruments — directly in your browser. No OMNIC software, no Thermo hardware connection required.
Native SPA/SPG parsing is on our roadmap. In the meantime, you can export your SPA data as SPC, CSV, or JCAMP-DX from OMNIC, then open it in SpectralBench for viewing and further conversion.
Yes. Upload your .spc file, preview the spectrum to confirm it parsed correctly, then export to CSV, JCAMP-DX, JSON, or MATLAB format. The entire conversion runs in your browser.
No. SpectralBench processes every file 100% client-side using JavaScript in your browser. Your spectral data never leaves your machine.
SPC is the native format for many Thermo Fisher (formerly Nicolet) instruments, including the Nicolet iS series (iS5, iS10, iS20, iS50), Nicolet Summit, and Evolution UV-Vis spectrometers. Older GRAMS/AI software also uses SPC format.
OMNIC requires a Thermo Fisher instrument connection or hardware dongle. OMNIC Paradigm uploads your data to Thermo's cloud servers. SpectralBench works without any hardware and keeps your data entirely on your machine.
