SPECTROview
An Open-Source Application for Interactive Spectroscopic Data Processing, Fitting, and Visualization
SPECTROview is a free, open-source software designed for advanced spectroscopic data analysis.
It supports discrete spectra and hyperspectral datasets such as 2D maps and wafer maps,
with integrated visualization tools that streamline your analytical workflow.
