    "abstract": "We present an optical system designed to capture and observe a single neutral\natom in an optical dipole trap, created by focussing a laser beam using a large\nnumerical aperture N.A.=0.5 aspheric lens. We experimentally evaluate the\nperformance of the optical system and show that it is diffraction limited over\na broad spectral range (~ 200 nm) with a large transverse field (+/- 25\nmicrons). The optical tweezer created at the focal point of the lens is able to\ntrap single atoms of 87Rb and to detect them individually with a large\ncollection efficiency. We measure the oscillation frequency of the atom in the\ndipole trap, and use this value as an independent determination of the waist of\nthe optical tweezer. Finally, we produce with the same lens two dipole traps\nseparated by 2.2 microns and show that the imaging system can resolve the two\natoms.",
