SPECTROview : A Tool for Spectroscopic Data Processing and Visualization.

SPECTROview is free, open-source software designed for spectroscopic data analysis. It supports a wide range of data types, including discrete spectra and hyperspectral data (such as 2D maps and wafer maps).

With its built-in visualization tools, SPECTROview streamlines your workflow by combining data processing and visualization into a single, efficient application.

• Installation: Instructions can be found at the bottom of this page.

• Getting Started: Check out this folder to see the supported data formats and find example datasets for practice.

• Documentation: A detailed manual is available here or can be accessed directly within the application.

Features:

• Cross-platform compatibility (Windows, macOS, Linux).
• Supports processing of spectral data (1D) and hyperspectral data (2D maps or wafer maps)*.
• Ability to fit multiple spectra or 2Dmaps using predefined models or by creating custom fit models*.
• Collect all best-fit results with one click.
• Optimized user inferface for easy and quick inspection and comparison of spectra.
• Dedicated module for effortless, fast, and easy data visualization.

*Fitting features are powered by the fitspy and lmfit open-source packages.
