Laser interaction with parchment in the near-ultraviolet and near-infrared wavelength range

  • A detailed diagnostic study of the interaction of nanosecond laser pulses from the near-ultraviolet into the near-infrared wavelength range with various types of contemporary and ancient parchments is presented. The advantages of laser cleaning due to the absence of chemical agents, spectroscopic selectivity, micro-precision, computer-aided handling can only be verified when physico-chemical diagnostics guarantee destructionless processing. Scanning Electron Microscopy (SEM) data are correlated with morphological changes in dependence on the laser fluence and wavelength. The question, to what extent the chemical degradation of collagen is affected by various laser treatment parameters, could be resolved by Transmission Electron Microscopy (TEM) of collagen fibres collected from the outermost laser-exposed surface layer. It is also shown how Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFT), and Pyrolysis Capillary Gaschromatography (PY-CGC) can be employed in theA detailed diagnostic study of the interaction of nanosecond laser pulses from the near-ultraviolet into the near-infrared wavelength range with various types of contemporary and ancient parchments is presented.

This study suggests that the ageing status of parchment artefacts plays a major role in assessing the laser cleaning limits.zeige mehrzeige weniger
