Holo/Or Ltd. has added elements to its Multi Spot series pattern generators that produce a 2-D array with eight spots arranged in a 3 × 3 array with a missing spot in the center. Applications include splitting an intense beam into several channels. The optics can be manufactured for 266, 532, 632.8, 1064, 1550, 2940 and 10,600 nm and at custom separation angles. Theoretical diffraction efficiency for the five points is close to 72%, and transmission efficiency is close to 100%. The standard element has a separation angle of 0.57° at 1064 nm. A single focusing lens can transform the beams into spots. The optics measures 11 mm in diameter and 3 mm thick. The 1064-nm model is made of pure fused silica.
