Sensor & Payload
Near-Infrared Spectroscopy
Use it for fast, repeatable screening where composition can be linked to calibrated spectral features.
Technology overview
How it works
Measures broad overtone and combination absorption bands associated mainly with C–H, O–H and N–H bonds, then relates them to reference values through chemometric or AI models.
Where it adds value
Coal and bulk-material quality screening; food / agricultural materials; seeds and grains; powders; at-line and inline process quality control.
Combine it with
Pair with LIBS for elemental information; THz for internal / moisture / dielectric information; automated sampling for repeatable industrial operation.
Practical note
NIR is model-driven: robust deployment requires representative reference data and ongoing calibration control.
Engineering principle: start with the measurement question, then select the minimum sensing stack required.
