BASIC IN OPTICS
This course provides an introduction to concepts of optics that are useful in understanding several techniques used in chemistry. Starting from basic notions, we will deal with the main properties of light, and with several classical phenomena. By using these elements, it will be possible to discuss the operation and the performances of optical devices and instruments. As an example, the instrumentation for Raman microscopy will be analyzed in detail.
The course aims at providing the basics of Optics in preparation for advanced chemical disciplines. The following subjects are dealt with: the properties of light radiation from thermal, laser and LED sources; the main phenomena of interference and diffraction; the definition of the various polarization states of a radiation.

Oral assessment with questions on the theory and simple calculations
The questions test the students' understanding of basic concepts in optics and their ability to apply such concepts for the description of the working principles of the devices introduced during the lectures.
Except for a few specified cases, the students will not be required to memorize formulas, but they will be required to show their ability to use them for the evaluation of optical quantities.
The questions will also test the student's knowledge of the order of magnitude of some properties of light and of some quantities characterizing the typical performance of the optical devices and instruments that have been introduced.
