Formula for Calculating Fiber Coupling Efficiency
The Fiber Coupling Efficiency is calculated using the formula:
Fiber Coupling Efficiency (%) = (2 * Numerical Aperture * Beam Diameter) / (π * Fiber Core Diameter) * 100.
Several terms in this formula need to be specified:
- Numerical Aperture (NA) – This is a dimensionless number that characterizes the ability of the fiber to gather light.
- Beam Diameter (mm) – This refers to the diameter of the light beam that enters the fiber.
- Fiber Core Diameter (mm) – This represents the diameter of the fiber’s core, which is the part where light is guided.
