Q-plates (QP) have become ubiquitous in experiments requiring the generation of vortex beams since its development in 2006. It consequently follows that it is important to characterize the vortex beams created by this geometric-phase optical element. Operation of a q = 0.5 QP is experimentally demonstrated along with characterization of the beam in terms of a special case of Hypergeometric-Gaussian modes through decomposition into Laguerre-Gaussian (LG) modes
