The maximum angle to the axis (centre line) of an optical fibre at which a light ray will enter the core and be propagated. Light striking the optical fibre at an angle greater than the Acceptance Angle will be lost.
Acceptance angle is the maximum angle at which incoming sunlight can be captured by a solar concentrator. Its value depends on the concentration of the optic and the refractive index in which the receiver is immersed. Maximizing the acceptance angle of a concentrator is desirable in practical systems and it may be achie...Found on http://en.wikipedia.org/wiki/Acceptance_angle_(solar_concentrator)
half the vertex angle of that cone within which optical power may be coupled into bound modes of an optical fibre NOTE 1 - Acceptance angle is a function of position on the entrance face of the core when the refractive index is a function of radius in the core. In that case, it is: where n (r) is the refractive index and n2
