Quantum Cascade Laser for Micro/Nanometric Spectroscopy - QCL MIRcat

Lingua Italiano

The MIRcat-xB is a field-proven multi-quantum cascade laser system. It features high-speed tuning, high spectral repeatability, improved thermal management fro room-temperatire operation without a cooling system, and long-wavelength option to the first generation of QCLs. The MIRcat is truly a one-box, fully automated system with a flexible, modular design that allows factory configuration of up to four pulsed or continuous wave/pulsed modules, plus the option to add or upgrade modules later.

A methodological approach to study the stability of selected watercolours for painting reintegration, through reflectance spectrophotometry, Fourier transform infrared spectroscopy and hyperspectral imaging

The aim of this work is to investigate the stability to simulated solar radiation of some paintings samples through a new methodological approach adopting non-invasive spectroscopic techniques. In particular, commercial watercolours and iron oxide based pigments were used, these last ones being prepared for the experimental by gum Arabic in order to propose a possible substitute for traditional reintegration materials.
