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.

• AI Chat Agent

  ---

  Talk to SPECTROview in plain language to filter data, run analyses, and create or customize multiple plots — powered by your own local (Ollama) or cloud LLM.
