Birefringence Properties of Optical Materials (0.12 μm

WebVacuum birefringence results in at least two different light speeds, and therefore two different light cones. As long as both light cones correspond to light speeds less than or equal to c, it's okay. Vacuum birefringence per se does not necessarily occur in QED since it hasn't yet been detected experimentally. 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.
