DBS-8x8 - Two-dimensional Beam Splitter

8x8 beam splitter diffracts the input beam into 64 beams. The power in each beam in ratio to the input power is > 1 % and the uniformity error (power in 64 beams to each other) is < 10 % (max-min)/(max+min). Power in the highest unwanted diffraction order is < 0.1 %.
