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.

θm = sin-1((1/ηo) * (ηf2c2)1/2) Where, θm = Acceptance Angle ηo = Exterior Refractive Index ηf = Fibre Refractive Index ηc = Cladding Refractive Index
