Birefringence
Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light.

Conoscopic interference pattern
A conoscopic interference pattern or interference figure is a pattern of birefringent colours crossed by dark bands (or isogyres), which can be produced using a geological petrographic microscope for the purposes of mineral identification and investigation of mineral optical and chemical properties.

Isotropy
Isotropy is uniformity in all orientations; it is derived from the Greek isos (ἴσος, "equal") and tropos (τρόπος, "way").

Mineral
A mineral is a naturally occurring chemical compound, usually of crystalline form and not produced by life processes.

Optic axis of a crystal
An optic axis of a crystal is a direction in which a ray of transmitted light suffers no birefringence (double refraction).

Optical mineralogy
Optical mineralogy is the study of minerals and rocks by measuring their optical properties.

Petrographic microscope
A petrographic microscope is a type of optical microscope used in petrology and optical mineralogy to identify rocks and minerals in thin sections.

Polarization (waves)
Polarization (also polarisation) is a property applying to transverse waves that specifies the geometrical orientation of the oscillations.

Thin section
In optical mineralogy and petrography, a thin section (or petrographic thin section) is a laboratory preparation of a rock, mineral, soil, pottery, bones, or even metal sample for use with a polarizing petrographic microscope, electron microscope and electron microprobe.
