PDF-Halite cubic sodium chloride crystal optically isotropic Calcite optically anisotropic

This effect was explained by Christiaan Huygens 1629 1695 Dutch physicist as double refraction of what he called an ordinary and an extraordinary wave With the help of a polarizer we can easily see what these ordinary and extraordinary beams are Ob.
