PROBLEM TO BE SOLVED: To provide an optical tweezers device capable of certainly catching a plurality of micro bodies according to a high definition pattern. SOLUTION: Laser light of high strength radiated from a fiber array light source 112 is modulated by a DMD (digital micromirror device) 110, and gathered by a micro lens array 130. The gathered laser light is made incident on corresponding optical fiber cores arranged in a matrix on an array head 132 to guide light in the optical fiber. The laser light is emitted from an end portion of the optical fiber. The plurality of the optical fibers is two-dimensionally arranged according to a plurality of pixel portions of the DMD 110, so that the laser light of high strength according to an on/off pattern of the DMD 110 is emitted from the array head 132. Therefore, the micro bodies existing on a stage 132 are certainly caught according to the high definition pattern. COPYRIGHT: (C)2005,JPO&NCIPI
