Refractive index glass

Many materials have a well-characterized refractive index, but these indices depend strongly. Fused silica (a pure form of glass, also called fused quartz), 589. In optics, the refractive index or index of refraction n of a material is a dimensionless number.

In general, the refractive index of a glass increases with its density. However, there does not exist an overall linear relation between the refractive .

Refracting optical materials are specified by their refractive indices for a. Optical glasses are available in a wide range of refractive indices and dispersions. The index of refraction and Abbe number of a glass are typically used by designers as degrees of freedom when designing systems.
