SpectralBench
Free Raman spectrum viewer — works with exported LabSpec and WiRE data
Horiba (LabSpec/LabRAM) and Renishaw (inVia/Qontor) are two of the most widely used Raman spectroscopy platforms in research labs worldwide. Each stores data in its own proprietary format — Horiba uses a binary format readable only by LabSpec, while Renishaw uses the WDF format readable only by WiRE software.
This makes it difficult to share Raman data between research groups, compare results from different instruments, or access your spectra when you're away from the instrument computer. Both LabSpec and WiRE licenses are tied to specific instruments, so you can't simply install them on your laptop.
SpectralBench works with Raman data exported from LabSpec and WiRE in standard formats. Export your spectra as CSV, JCAMP-DX, or SPC from your instrument software, then open them in SpectralBench for viewing, analysis, peak detection, and format conversion — all in your browser, with no data uploaded.
SpectralBench correctly handles Raman shift (cm⁻¹) on the x-axis and provides peak detection tailored for Raman spectroscopy. Compare spectra from different instruments side by side, or convert between formats to share with collaborators using different platforms.
Native format support: Direct parsing of Horiba binary and Renishaw WDF files is on our roadmap. For now, export your data from LabSpec or WiRE as CSV, JCAMP-DX, or SPC — SpectralBench reads all three natively.
In LabSpec: File → Export → CSV/JCAMP. In WiRE: File → Export → Text/CSV. This takes seconds.
Drop the exported file onto SpectralBench. Interactive Raman spectrum with zoom, peak detection, and annotation.
Export to any format — CSV, JCAMP-DX, JSON, MATLAB. Share with collaborators on any platform.
SpectralBench supports spectral data from any instrument, not just Raman:
SpectralBench reads CSV, JCAMP-DX, and SPC exports from LabSpec. To use SpectralBench, export your data from LabSpec as CSV or JCAMP-DX, then drop the file onto the viewer. Native Horiba binary format support is on our roadmap.
Native WDF parsing is planned. For now, export your Raman data from Renishaw WiRE software as CSV or JCAMP-DX, then open it in SpectralBench for viewing, analysis, and conversion.
Yes. SpectralBench correctly handles Raman shift (cm⁻¹) on the x-axis and provides peak detection tuned for Raman spectra. It supports SPC files with Raman shift x-type labels and JCAMP-DX files with Raman data types.
Yes. Load Raman spectra from Horiba, Renishaw, or any other instrument and SpectralBench overlays them with color-coded traces. Use the Compare tool for HQI similarity scoring and spectral subtraction.
No. SpectralBench processes every file 100% client-side in your browser. Your spectral data never leaves your machine.
