ABSTRACT:
An apparatus minimizes the spherical aberration of a light beam emitted into an optical fiber from a light source such as a laser beam. The laser emits a light beam along a path of travel to an optical fiber used in a telecommunication system. A ball lens is positioned within the light beam path of travel, and has a front focal point. The laser is positioned in front of the front focal point such that the light beam emitted by the laser forms an intermediate paraxial focus point. A corrective lens is positioned adjacent the paraxial focus point so that the laser beam is introduced into an optical fiber with minimal spherical aberration and increased coupling efficiency. The corrective lens is displaced radially off-center to compensate for misalignment aberrations and coma.
