"Researcher's life made easy — powerful spectral analysis tools, free for the world."
BRIGHT Lab is committed to making cutting-edge spectral analysis accessible to researchers everywhere. Our free web tools let you upload your Raman data and apply advanced statistical and machine learning methods — no coding required.
Principal Component Analysis, Linear Discriminant Analysis, Quadratic Discriminant Analysis
Upload your raw Raman spectral data and instantly visualize sample groupings through interactive plots. Identify hidden patterns, reduce dimensionality, and explore variance across your dataset — all in your browser, no installation needed.
More tools are actively being developed. Check back soon!
Normalization & Baseline Correction
Clean your Raman spectra before analysis — apply fluorescence baseline correction, vector normalization, smoothing (Savitzky-Golay), and cosmic ray removal.
SVM, Random Forest & More
Train and test machine learning classifiers on your spectral data. Compare SVM, Random Forest, and k-NN with cross-validation and performance metrics — all in one click.
Open access resources
Resources for learning and reference in Raman spectroscopy and related fields of biomedical research.
Upload your Raman spectral data as a CSV or Excel file. Rows are samples, columns are wavenumber intensities.
Set your parameters — number of components, class labels, preprocessing options — and click Run.
Interact with scores plots, loadings, and statistics. Download publication-ready figures and result tables.
