WebAn optic axis is a direction rather than a single line: all rays that are parallel to that direction exhibit the same lack of birefringence. [1] Crystals may have a single optic axis, in which case they are uniaxial, or two different optic axes, in which case they are biaxial. Non-crystalline materials generally have no birefringence and thus ... WebJ. Opt. Soc. Am.

WebAs birefringence increases, the colors repeat (see figure below), but get more and more pastel (washed out). To describe interference colors we must specify both a hue and an order (e.g., 2nd order red; see chart below). Minerals with low birefringence show only white, gray and black interference colors. WebOptics 4 2 • The birefringence of a mineral grain is defined as the absolute value of the difference between the refractive indices of the two rays n S - n F for that grain. The maximum birefringence of a mineral is defined as the difference δ between the largest and smallest refractive indices for that mineral. hunkerson gap rd mathias wv 26812

WebA study of photoinduced birefringence in bow-tie (stress-induced) high-birefringence (Hi-Bi) and low-birefringence (Lo-Bi) germanosilicate optical fibers is conducted by using 532-nm light. The study reveals that Hi-Bi fibers are insensitive to light polarized along the fast axis, in contrast to Lo-Bi fibers, which are photosensitive along both axes.
