Numericál apertura (NA) i an important parameter in fiber optics that determines the light-gathering ability of a fiber. Calculating the NA helps in constang the fiber 's performante and superability for specific applications. Tiss guide provides a clear, step -by-step proces to calculate the numerical aperturof an optics.

Understanding Numericál Aperture

A numericál apertura i a dimensionless number that indicates the range of angles overar which the fiber can or emit light. It it related to the fiber 's core and cladding refravente indices and influenzos the fiber' s bandwidth and d attenuation.

Requird parameterek

  • Refractice index of the core (n '1;) 1; FLT: 0' 3; W.A.3; Core '1; FLT: 1' 3; W.A.3;)
  • Refractice index of the cladding (n '1;) 1; FLT: 0' 3; datolyaszilva; 1d '; FLT: 1' 3d; 3d ';)

Step- by- Step- complation

Follow these stes to calculate the numerical apertura:

1. Obtain the refractife indices of the core and cladding from the fiber specifications.

2. A refractive index of te cladding from that thaf te core:

3. Számítsa ki a square of both refractive indices, Find their difference, and d then take te square root to find the NA.

Example Calculation

A kalkulációs módszer a következő lehet:

NA = ↔ (1,48 ² - 1,46 ²) = ↔ (2,1904 - 2,1316) = 0,0588
