Cultural Heritage & Conservation

Map pigments, distinguish original materials and overpaints, and monitor degradation without physical sampling.

Outcome
See subtle variations while preserving their exact position on the object.
Evidence
Pigment maps, calibrated colour, reflectance curves and spatially resolved condition documentation.
Range
Illustrative range: 300–1000 nm
