Stevi Jackson,Petula Sik Ying Hod somewhat more completely. Crystals may be elongated parallel to either X, Y, or Z, or to none of these. Crystals elongated parallel to Y are considered to have an indeterminate (±) sign of elongation.

Crystal optics continues to be a developing branch of physics, and has many ramifications beyond determinative work. The nature of light and its behavior have formed a central part of physics since its earliest days, from Snell in 1621 through such c

Stevi Jackson,Petula Sik Ying Hoin identification in immersion mounts are those related to refractive index, optic sign, and color. In thin section, the most useful optical properties are relief, birefringence, and optic sign. Crystallographic properties that are most useful include those related to crystal habit, cleavage, and tw

With many of these, knowledge of the optic sign and the three refractive indices is of prime consideration, but while these properties are being measured, one often gains knowledge of other useful properties such as birefringence, pleochroism and absorption, di
