An optoelectronic apparatus includes an array of emitters configured to emit respective beams of optical radiation. Projection optics include first cylindrical lenses, which have respective, mutually-parallel first cylinder axes, and are aligned respectively with the emitters in the array so as to receive and project the respective beams, and a second cylindrical lens, which has a second cylinder axis perpendicular to the first cylinder axes and is positioned adjacent to the first cylindrical lenses so as to receive and project all of the beams from the first cylindrical lenses.
