This paper reports the use of free space zeroth-order Bessel beams for the optical manipulation of trapped microscopic particles. A conically shaped optical element was used, with an internal angle of one degree to generate Bessel beam. A simple telescope was used to reduce the size of the central maximum of the Bessel beam to about 8 microns in diameter. The Bessel beam had an overall propagation distance of about 5 mm in this instance. This beam was used to trap and manipulate silica spheres.
