A total of 100 beams emitted from 100 stripes, with an 80-μn aperture spaced on 100-1μm centers, of a l-cm linear diode array were collimated by a multiprism array consisting of 15 800-μm-wide prismlets. The spatial intensity distributions of each eight-beam unit were rotated 90℃through three total reflections in a prismlet. The array of prismlets transforms a long dotted line (a long line away of emitters) to a series of short dotted lines arranged in parallel. Collimated beams were focused to a spot of -500 μm (FWHM). #1997 Optical Society of America
