Abstract
A combination for use in optical trapping is provided, comprising, in series: an adaptable reflective optical element for sculpting a laser beam to produce a sculpted beam; a beam splitter for splitting the sculpted beam into a first and a second sculpted beam; a micro lens array for dividing the first sculpted beam into an array of beamlets to produce a plurality of focal points; relay optics; and a focusing lens; and, in parallel: a wavefront curvature sensing device for accepting and analyzing the second sculpted beam, and reporting to a computer.
