Among the beam diagnostics routinely employed in source for production of ion of deuterium (SPIDER), beam emission spectroscopy (BES) provides valuable information for beam characterization, thus driving source optimization methods. In particular, this technique is used to measure beam divergence and uniformity, which are crucial parameters to be optimized for application in International Experimental Thermonuclear Reactor (ITER). In this contribution, we focus on the characterization of H-/D- beamlets extracted during the first SPIDER Cs campaigns. In particular, we show parametric scans and preliminary broad component estimates on single beamlets.
