How to Evaluate Refractive Index of Cladding?

Refractive Index of Cladding evaluator uses Refractive Index of Cladding = sqrt(Refractive Index of Core^2-Numerical Aperture^2) to evaluate the Refractive Index of Cladding, The Refractive Index of Cladding formula refers to the optical property that describes how light propagates through the outer layer (cladding) of an optical fiber. It is a measure of the speed at which light travels in the cladding material compared to its speed in a vacuum. Refractive Index of Cladding is denoted by η_clad symbol.
