Spectra Viewer helps you prepare gamma-spectrum charts for reports, scientific papers, educational materials, presentations, documents, and print.

The application is designed for viewing, comparing, and analyzing gamma-spectrum files on Android devices. Open supported spectrum files and inspect data by channel or calibrated energy.

• Open supported gamma-spectrometry files
• Display spectra by channel or calibrated energy
• View multiple spectra on a single chart
• Normalize, compare, and subtract spectra
• Use background spectra
• Zoom charts and inspect values
• Customize line color, width, style, opacity, and fill
• Export charts as PNG, SVG, and PDF
• Prepare spectrum images for documents, publications, presentations, and print
• Save spectra in supported file formats

PNG is convenient for quickly adding charts to documents and presentations. SVG preserves vector quality when scaled and can be used for further editing. PDF is suitable for sharing, archiving, and printing.

Spectra Viewer is intended for technical, educational, and research work with previously recorded spectral data.

The application does not measure radiation and is not a substitute for certified radiation-detection instruments or radiation-safety equipment.
