Iceland Spar: The Rock That Lens Rentals | Blog

· A crystal of Iceland spar has two very interesting properties First, it is a natural polarizing filter Second, because of its natural polarization, Iceland spar is birefringent, meaning light rays entering the crystal become polarized, split, and take two paths to exit the crystal – creating a double image of an object seen through the crystal There is good evidence that the Vikings used
