Brief description of the lecture:
Basic concepts in optics (interference, reflection, refraction, total internal reflection). The spread of light in isotropic and anisotropic medium. The polarized light. The optical characteristics of crystals. Optical indicatrix. The construction and elements of the petrographic microscope (light source, Abbe condensor, analyser-polariser, Bertand lens, ocular). Auxiliary slides, compensators. Defining the optical characteristics of minerals (refractive index, double refraction, extinction, extinction angle, sign of elongation, optical character).
The indicatrix of uniaxial and biaxial minerals. The elements of mineral classification. Opaque minerals. Optical classes of minerals: isotropic and anisotropic minerals. The classification of rock-forming minerals.
