sci.fiber-optic-numerical-aperture Calculator
Calculates numerical aperture of an optical fibre: NA = √(n_core² − n_clad²) and maximum acceptance angle θ_max = arcsin(NA). Silica SMF-28: NA = 0.14, θ_max = 8° — multimode graded-index fibre with NA = 0.22 accepts light over ±12.7° half-angle.
Inputs
N Core
Reference formula or conversion factor shown for context.
N Clad
Reference formula or conversion factor shown for context.
Results
numerical aperture NA
Sample size or count used in the calculation.
acceptance angle θ_max (°)
The computed angle in degrees or radians.
relative index difference Δ
The arithmetic difference between the two values.
NA = √(n₁²−n₂²)
Sample size or count used in the calculation.
single-mode condition
The most frequently occurring value.
fiber type
The classification or type assigned based on the inputs.
