WebIn optical mineralogy and petrography, a thin section (or petrographic thin section) is a thin slice of a rock or mineral sample, prepared in a laboratory, for use with a polarizing petrographic microscope, electron microscope and electron microprobe. A thin sliver of rock is cut from the sample with a diamond saw and ground optically flat. WebThe Optical Indicatrix. Shows how n. i. varies with vibration direction. Vectors radiating from center. Length of each proportional to n. i. for light vibrating in the direction of the vector. Indicatrix = surface connecting tips of vectors (a representational construct only!) Isotropic media have all n. i. the same (by definition) WebThe optical properties of minerals are characteristic and serve for mineral identification. The subject of optical mineralogy is extensive and is dealt with in many excellent books (for a partial listing, see “Further reading” at the end of this chapter). dynamic exteriors
