The present disclosure relates to an apparatus () and method for controlling a plurality of simultaneously active optical traps (OT,OT,OT). In one method, trapping beams (TB,TB,TB) are provided and redirected for individually controlling a respective position (X,Y) of optical traps (OT,OT,OT) formed by focusing of the redirected trapping beams in a sample volume (SV). Light (L,L) 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 (TB), wherein the detector beam has a distinct wavelength (&#x3bb;A) from that of the overlapping trapping beam (TB). In one channel, the light from the sample volume is filtered according to wavelength, and only the filtered light having the wavelength (&#x3bb;A) of the detector beam (AB) is measured.
