Multi-beam optical system using lens array

摘要: Each laser of a semiconductor array an optical system has its own lens mounted adjacent to it in the space between and objective system. The purpose lenses is change angle divergence light beams leaving emitting surface so that can be collected efficiently by lens, thereby providing significant beam power at sensitive medium (optical disk, photoconductor, etc.) focusing each chosen form virtual images behind with spacings approximately corresponding emitted array, but emitter image size substantially magnified.
