Spectra Lab puts NIR calibration on trial
A set of free NIR calculators and guided demonstrations explain how to build and validate calibration models, with a browser-based lab offered through an early-access waitlist.
- For
- NIR practitioners validating quantitative calibrations
- Worth noticing
- The teaching subset is labeled CC BY 4.0 and covers scans at 103 points from 684 to 990 nm.
Field notes
The teaching walkthrough starts with 600 whole mangoes measured against laboratory dry-matter values, then moves through spectra, preprocessing, PLS component selection, and validation. Its held-out test uses 100 fruit from a fourth season, and the page labels the teaching subset CC BY 4.0. A separate calculator accepts pasted reference and predicted values, while the broader import-and-fit browser lab is presented as an early-access waitlist.
