SPECTROview is a free, open-source software application designed for advanced spectroscopic data analysis. It supports a diverse array of data types, including discrete spectra and hyperspectral datasets such as 2D maps and wafer maps. With its integrated visualization tools, SPECTROview streamlines your analytical workflow by consolidating data processing and visualization into a single, cohesive application.

Key Features¶

High-Performance Vectorized Batch Fit Engine (VBF Engine)

Achieves very fast fitting speeds through batched matrix operations, capable of simultaneously fitting multiple spectra or large 2D maps.
Custom Fit Models

Construct customized fit models for specific spectroscopic profiles and reuse them to rapidly analyze new datasets.
Versatile Data Processing

Seamlessly process both 1D spectral data and 2D hyperspectral data.
Unified Results

Collect and compile all best-fit results with a single click.
Advanced Visualization

Dedicated workspace for generating fast, publication-ready data visualizations.
Optimized User Interface

Designed for quick inspection, filtering, and comparison of large spectral datasets.
