Measurements of absorption, remission, reflection and photoacoustic (IR) spectra and colorimetric data of liquids and solids of different internal and surface structure in UV, Visible and IR spectral regions, including different transmission and reflection measurement techniques: simple transmission, single reflection at different angles, diffuse reflectance in UV, Vis. and in IR (DRIFT), special reflection techniques in IR (Diamond ATR, MIR ATR, HATR, photoacoustics), including spectral IR microanalysis using FTIR microscope VARIAN and portable fibre-optics spectrometer OceanOptics

  • Molecular spectroscopy, chemical analysis of function groups in a bulk and/or at a surface.  - Thin film analysis, spectral and optical properties of layers, foils, powder materials
  • Colorimetry of materials, color coordinates, color difference, whiteness, brightness,...
