Short Description
The FTIR-microscope LUMOS II enables molecule-specific analyses of organic and inorganic samples. A high spatial resolution and a relatively large sampling stage allow the investigation of microsamples as well as selected areas on larger samples. Various operation modes and detectors offer a wide range of applications, such as characterization and identification of pigments, binders, synthetic polymers, etc. in microsamples and cross sections of embedded samples originating from art objects or archeological findings.
Depending on sample characteristics the analyses are conducted by using transmission-, reflection- or ATR-mode (attenuated total reflection). The instrument is equipped with a liquid nitrogen cooled FPA detector (32 x 32 pixels) for imaging and mapping applications in a spectral range of 5000-750 cm-1 (cm superscript minus 1), a liquid nitrogen cooled broad band MCT detector for single point analyses in a spectral range of 7800-450 cm-1 (cm superscript minus 1), as well as a DLATGS detector with limited spatial resolutions > 30 µm. Moreover, a macro unit allows coupling of the QuickSnap sampling modules of the spectrometer ALPHA II (ATR, external reflection, transmission) for the analysis of larger samples.

Research Services
The Institute for Natural Sciences and Technology in the Arts (INTK) and the Core Facility "Centre for Material Sciences in Art and Conservation (ZMKK)" are central facilities of the Academy of Fine Arts Vienna for the natural scientific (material) analysis of works of art. The facilities support members of the Academy of Fine Arts Vienna or other research institutions, museums, libraries, archives, etc. in the realisation of joint projects within the framework of research funding or contract research and also offers services (third-party funding) for external parties.
The focus is on scientific material analyses of artworks and archive materials using FTIR, Raman, XRF, UV-Vis, HSI, RSI, ESEM (EDX), Py-GC/MS, digital X-ray radiography and photo documentation (Vis, UV, IR, IRR), microscopy, chambers for accelerated ageing of samples.
