Refractive Index of Fiber Core evaluator uses Refractive Index of Core = sqrt(Numerical Aperture^2+Refractive Index of Cladding^2) to evaluate the Refractive Index of Core, The Refractive Index of Fiber Core formula is refers to the optical property that describes how light propagates through the core of an optical fiber. It is a measure of the speed at which light travels in the core material compared to its speed in a vacuum. Refractive Index of Core is denoted by ηcore symbol.
How to evaluate Refractive Index of Fiber Core using this online evaluator? To use this online evaluator for Refractive Index of Fiber Core, enter Numerical Aperture (NA) & Refractive Index of Cladding (ηclad) and hit the calculate button.
