Raman Spectroscopy for Pigments Checker

Maria Cristina Caggiani, PhD, expert in spectroscopic techniques for the study of cultural heritage is analyzing Pigments Checker with Raman Spectroscopy (Horiba-Xplora Raman Spectrometer with 3 excitations, 532, 638 e 785 nm), Horiba is thanked for their support. Maria Cristina answered the call for collaborators for this new project. We want make Pigments Checker a valid tool for Scientific [...]

Pigments Checker New Version (2.1)

We released Pigments Checker v.2.1. We constantly add features to improve this tool: It comes with our new Multispectral Imaging calibration card. Commercial gray cards for photography cannot be used for multispectral imaging since they absorb near UV and violet radiation. We developed a gray card to cover the 400-1000 nm spectral range. It has 6 swatches, [...]
