Abstract: Optical trapping is an increasingly important technique for controlling the structure of matter that has mainly applications in biophysics and medicine. This article finds the way to maximaze the linear region of the radial force profile in Optical tweezers. We take attention on simulations, where it can be controlled the force profile and see how conffigurations of two and three very close traps affect to particles. Then the simulation results are compared with experimental force profiles of 1.87um polystyrene beads to determine if truly the linear region has been elongated.
