Abstract (en)
[origin: WO02093202A2] The present invention relates generally to generating and controlling optical trap arrays for manipulating particles. In particular, the invention relates to a dual function optical element able to both diffract laser light into beamlets and converge the beamlets (acting as a virtual lens for laser light), thereby eliminating the need for multiple physical lenses to transfer the diffracted laser beams to a focusing lens. The invention also relates to improved monitoring of optical traps by limiting the amount of noise reflected and scattered resulting from un-diffracted, laser light.
[origin: WO02093202A2] An apparatus to produce and monitor at least two optical traps (1002, 1004) comprising a phase patterning element (12), a single transfer lens (L1), a beam splitter (51).
