4 19mm coated iridescent reflective glass facade dazzle colored glass

Dichroic glass, also often called "rainbow glass", "Dazzle Color glass" or "reflective color-changing glass", this glass material, when you look at it from different angles, its color also changes when it encounters Light, the surface of which will appear in one color and pass through the glass, but presents another color that is completely different from glass, like a rainbow shattered and mixed inside.

Principle of dichroism: When a bundle of monochromatic light is refracted on the surface of the crystal (as shown), two beams of refracted light are generally produced. This phenomenon is called birefringence. One of the two refracted lights always obeys the law of refraction, called ordinary light, which is represented by the symbol o; the other beam generally does not obey the law of refraction, called extraordinary light, and is represented by the symbol e. Both o and e are linearly polarized. Most crystals produce equal intensity of o and e light in the case of natural light. However, some crystals have a large difference in the absorption of two refracted lights. This property is called dichroism.
