The ISAAC Research Centre has developed a series of versatile and modular spectral imaging systems (PRISMS) that enables automated high spatial resolution imaging from remote distances of tens of metres (80 micron resolution at distance of 10m) to close range imaging in the microscopic mode (a few micron resolution), from hyperspectral to broad band imaging. They are suitable for the examination of the paintings to reveal the underdrawings using the near-infrared band as well as the pigment identification at a pixel level. The spatial and spectral parameters of the spectral imaging systems are shown below.
