WebGems that polarize light and split it into two (or three) different directions are said to be doubly refractive. Birefringence is a measure of a gem's double refraction. It serves as one of the principal ways gemologists can identify gems. Natural zircon (not to be confused with cubic zirconia) has been used to create convincing diamond imitations. WebThe index of refraction ranges from approximately 1.45 - 2 for visible materials and 1.38 - 4 for IR materials. In many cases, index of refraction and density share a positive correlation, meaning IR materials can be heavier than visible materials; however, a higher index of refraction also implies diffraction-limited performance can be achieved with fewer lens …
