摘要： The present disclosure relates to an apparatus (100) and method for controlling a plurality of simultaneously active optical traps (OT1,OT2,OT3). In one method, trapping beams (TB1,TB2,TB3) are provided and redirected for individually controlling a respective position (X,Y) of optical traps (OT1,OT2,OT3) formed by focusing of the redirected trapping beams in a sample volume (SV). Light (L11,L20) from the sample volume (SV) corresponding to the optical traps is received. A path of a detector beam (AB) is overlapped with one of the trapping beams (TB3), wherein the detector beam has a distinct wavelength (λA) from that of the overlapping trapping beam (TB3). In one channel, the light from the sample volume is filtered according to wavelength, and only the filtered light having the wavelength (λA) of the detector beam (AB) is measured.
