Dynamic Monitoring of Sensitivity of Materials to Light/Radiation (microfade testing and mitigation of radiation induced alteration)
A sensitive dynamic monitoring method to assess reflectance alterations for microfade testing of material sensitivity to light exposure, and the method can also be used as a monitoring method for the detection of both physical and chemical changes on historical material surfaces induced by intense radiations (e.g. lasers, synchrotron X-rays) used for material analysis.

Hybrid OCT @ 1350nm & Microscopic VIS/NIR Spectral Imaging (415-845 nm)
The Hybrid system combines optical coherence tomography (OCT) system with a reflectance spectral imaging system into one instrument. OCT provides 2D and 3D virtual cross-sectional images in a non-invasive and non-contact way. It is suitable for the investigation of translucent and transparent materials (e.g. varnishes, glass, glazes) in the near-infrared (central wavelength 1350 nm). VIS-NIR Spectral Imaging can provide identification of materials. The simultaneous use of the two analysis methods allows for a 1:1 spatial alignment between the spectral images and OCT 3D volumetric data sets, providing additional context on the layer structure.

Long Wavelength OCT @ 1960 nm
Long Wavelength Optical Coherence Tomography (OCT) provides 2D and 3D virtual cross-sectional images in a non-invasive and non-contact way. It is suitable for the investigation of surface and subsurface translucent and transparent materials (e.g. varnishes, glass, glazes) in the short-wave infrared (central wavelength 1960 nm) with a resolution of a few microns. This OCT is optimised to provide a larger penetration depth in materials than OCTs at shorter wavelength making it more suitable to the investigation of more scattering materials such as paints and enamels.
