Disposing aperture-truncated radiation of divergent beam in fiber optic collimators and arrays

摘要

An optics system includes at least one emitting fiber tip that transmits a divergent beam. The divergent beam includes a global maximum intensify of radiation centered with an output optical axis. The divergent beam includes central beams for collimating and periphery beams for disposing. The periphery beams include parasitic radiation of the divergent beam. The optics system includes at least one collimating lens having an output size, output shape, and output optical axis centered thereto and configured to redirect the central beams to a target and redirect the periphery beams into free-space; and at least one redirecting element positioned in between the at least one emitting fiber tip and the at least one collimating lens. The redirecting element includes a first area having an interior size and interior shape to transmit the central beams, and at least one second area outside of the first area to transmit the periphery beams.
