Acceptance Angle in Optical Fibre Calculator

The maximum angle which allows the incident ray to be guided by the core is called as the acceptance angle. In optical fibre, it is calculated based on the fibre, cladding and exterior refractive index.

Formula:

θ_m = sin^-1((1/η_o) * (η_f²-η_c²)^1/2) Where, θ_m = Acceptance Angle η_o = Exterior Refractive Index η_f = Fibre Refractive Index η_c = Cladding Refractive Index
