Acceptance Angle in Optical Fibre Calculator

Acceptance angle is the maximum angle which allows the incident ray against the fibre axis hitting the fibre core which allows the incident light to be guided by the core. It is calculated based on fibre, cladding and exterior refractive index. Use the online acceptance angle in optical fibre calculator to calculate the angle of acceptance in the optical fibre.
