A collection of analytical and imaging tools (3D digital microscope, micro-XRF, Raman microscope, variable pressure electron microscope, etc.) provides information on the structure and composition of the objects.

Digital 3D microscope: The first step in the investigation of cultural heritage objects is optical imaging. Besides the image, the digital 3D microscope yields quantitative information about the structural features of the object not only on a horizontal but also on a vertical scale. This is useful, for example, for determining the depth of carvings or the height of reliefs. Micro-XRF equipment: It is a tool for sample characterization using small-spot micro-X-ray fluorescence. The measurement gives quantitative information about the composition and distribution of elements. The spectrometer is optimised for high-speed analysis of points, lines, and 2D area scans (element mapping) of the samples. It works both in vacuum and in air and has a large chamber. Scanning electron microscope: It scans a focused electron beam over a surface to create an image. The electrons in the beam interact with the sample, producing different signals that can be used to obtain information about the surface topography and composition. The device also operates in a low vacuum. Raman microscope: In the case of Raman spectroscopy, the vibration spectrum can be used to obtain information on the type, position, and orientation of the functional groups in molecules. The compounds can be identified by their characteristic Raman spectra.
