01 Why GM-100
Large-instrument capability. Compact by design.
The power of a spectrometer. Without the lab.
Traditional color measurement relies on expensive spectrometers, while geometry measurement often requires a large dark laboratory. GM-100 brings accurate and stable color and spectral measurement into a compact field instrument.
AI-ENHANCED ACCURACY
More accuracy from every measurement.
A novel spectral sensor, individual unit calibration and AI-powered algorithms work together to improve measurement accuracy and temperature stability.
