Educational Objective: Different optical and spectroscopic techniques are used for chemical analysis. Of the optical devices the widely used are different types of microscopes, photographic devices and cameras. Of the spectroscopic techniques the methods of infrared and Raman spectroscopy for the analysis of traces (colour, ink, fibre, mineral residues, drugs shaped and of other substances). The aim of this subject is learning about, studying and acquiring basic knowledge in optics and spectroscopy for the application of these techniques and methods.

Projected Outcome: Acquiring basic knowledge on optical and spectroscopic components and techniques. Knowing different methods of optics and spectroscopy. Mastering the ability of obtaining and interpreting optical spectra.

Course Contents/Structure

Theoretical education: Definitions, classification and function of optical component and devices. Theoretical bases of absorption, emission and vibration spectroscopy for traces analysis. Light sources, dispersion elements and radiation detectors. The analysis of spectrum and system for vibration spectroscopy (Fourier transform infrared and Raman spectroscopy). Determining colours and pigments based on the absorption measurements.

Practical training: Laboratory exercises: getting to know particular optical and spectroscopic devices; Measuring optical transmission and infrared spectra of reflection and Raman spectrum. Identifying material based on infrared (IR) rays and Raman measurement.
