Description
2019 Honorable Mention, Northwestern Scientific Images Contest. The vivid colors and patterns you see are a result of birefringence, which is an optical property of anisotropic materials. Ordinary objects, like this plastic dish and tube undergo stress during manufacturing as the plastic is molded into its desired form. When you observe these objects through crossed polarizers, you are able to see the stress in the object as birefringent signal zones. Birefringence can tell us important information about the mechanical properties of various materials, such as crystals and polymers.
