More Optical Properties of Ulexite
Jay O'Brien
Abstract:
Ulexite, a mineral comprised of parallel optical fibers, has a property of taking incident light and refracting it into one, two, or three circular cones. The light starts to delete in intensity as it moves away from these cones. There is evidence that this may be due to the ulexite’s many fibers acting as diffracting slits. However, there is more compelling evidence that it may be due to leakage between adjacent fibers.
