Optical Fiber Acceptance Angle Calculation

Total internal reflection is the phenomenon where a ray of light traveling from a medium with a higher refractive index to a medium with a lower refractive index is reflected back into the higher index medium.

The critical angle is the minimum angle of incidence at which total internal reflection occurs.

The refractive index of sapphire is 1.80.
