Light travels through Optical CalciteOptical Calcite "Iceland Spar" from SpiritRock Shop,Double refraction occurs when a ray of light enters the crystal and due to calcite's unique optical properties, the ray is split into fast and slow beams. As these two beams exit the crystal they are bent into two different angles (known as angles of refraction) because theDouble Refraction | Harvard Natural Sciences Lecture,,Calcite usually occurs in an impure polycrystalline form as marble, limestone, or chalk. Optical calcite, or Iceland spar, is quite rare.
