Optics Laboratory

  • Interference from nearly monochromatic– (Laser) and pseudomonochromatic– (spectral lamps Na, Hg, He, etc.) and natural light–sources (incandescent lamps) by using specific interferometry setups (Lloyd, Newton, Michelson – theory of partial coherence of light -)
  • Fraunhofer- and Fresnel- diffraction from monochromatic and natural light sources with various diaphragms, (circular- and rectangular- apertures, single- and many- slits, gratings) using various diffractometry setups. Determination of the spectral lines wavelength by using grating diffractometers
  • Production, analysis and detection of various states of polarization (linear- , circular- , elliptic – polarized light) and their application to the phenomena of reflection and refraction.  A large part of the experiments is dedicated to crystal optics and specifically to the phenomena of double refraction of light, with the help Iceland spar.
  • Are studied the basic laws of geometrical optics (rectilinear propagation, reflection, refraction) as key applications and function in lens present in various optical systems (optical diopter , prisms , thin -, thick – , converging-  and diverging – lens systems , aberrations)
  • It is studied the phenomenon of light dispersion by prism (via spectroscopic setups) and its interpretation on the bases of the refractive index atomic model as well as the effect of the thickness (Beer’s law) and spectral distribution of incident beam on the absorption spectrum.
