Abstract
A system and method for aligning a microfilter in an optical circuit and thereby providing sub-beam impingement intensity control from a set of highly proximate sub-beams generated from a parallel process laser system removing a portion from a workpiece (exit holes in inkjet nozzle plates). The energy of laser-generated sub-beams to the target (cutting) point is attenuated to a level sufficient for maintaining operation of a charge-coupled-device camera below saturation when the sub-beams are incident on the camera, the CCD camera monitors the sub-beams and directs output to either a monitor or control computer. The microfilter is then adjusted to provide an optimal sub-beam pattern.
