Spectra Lab is where I put the near-infrared spectroscopy ideas I teach into tools you can use: free validation checks for bias, SEP, RMSEP and RPD, three guided journeys on real data, and a browser lab for PLS calibration.
Near-infrared spectroscopy reads how light passes through a sample to tell you what is inside. Before you trust a calibration you should check it, and these tools make that a ten-minute job instead of a spreadsheet afternoon.
It sits next to the SpectroScience course: the course explains, the lab lets you try. Early access is open.
