APPARATUS FOR APPLYING OPTICAL GRADIENT FORCE

摘要

PROBLEM TO BE SOLVED: To form a plurality of optical traps from a single light beam. SOLUTION: The invention provides an apparatus and method for manipulating small dielectric particles. The apparatus and method involve use of a diffractive optical element (40) which receives a laser beam and forms a plurality of laser beams. The beams are operated by a telescope lens system, and then by an objective lens element (20) to create an array of optical traps (50) to manipulating small dielectric particles.
