Abstract
An apparatus that efficiently and accurately directs or splits a non-polarized light beam input from a fiber optic into one, two, four or eight output beams wherein the light beam input is passed through a collimator, the apparatus uses non-polarizing beam splitters and the output beams are coupled to fiber optics using a lens matched to divergence of the beam to direct the beam into the fiber optic and uses an iris diaphragm attenuator to adjust the energy of the output beam prior to its entry into the fiber optic.
