A near-field-light lens for focusing of atoms on a nano-size spot is described in the paper. The device works as a lens with a focal length of 1.0 μm, a focal depth of 10 nm, and NA of 0.14 for Rb atoms with the velocity of 10 m/s in the case where the incident light intensity is 107 mW/cm and the blue detuning is 1.5 GHz.
