Twelve beams emitting from twelve stripes, with 200-microm apertures spaced 800 microm apart, of a 1-cm linear diode array were collimated by a multiprism array consisting of fourteen 800-microm-wide prismlets. The spatial intensity distribution of each beam was twisted around its optical axis through three total reflections in a prismlet, transforming a series arrangement of emitters into a parallel arrangement to prevent overlap of adjacent beams. Collimated beams were focused to a spot of ~200 microm (FWHM).
