Light distribution in the fibre with a spherical output surface

We have discussed transmission of the luminous flux through the optical fibre with a flat input surface and a spherical output surface. In this discussion we have considered the basic losses of the luminous flux.: Fresnel reflections, absorption of the core material on the optical path, and imperfections of the internal reflection. The curves of luminous intensity of the solids of light distribution in the optical fibre mating with a halogen bulb have been given as well.
