Figure 5
Crystals used in the multi-projection setup. (a) Drawing and (c) picture of a recombiner. The 2.5 mm large stress relief cuts are visible, giving an S-shape to the profile of the crystal. (b) Drawing of a diamond beam-splitter, light blue being the actual beam-splitter, yellow the polycrystalline frame and gray graphite used for fixing the two together. Two stress relief cuts are visible on the base of the beam-splitter near the clamping point with the graphite. (d) Picture of a mounted beam-splitter. Both for the recombiners and the splitters, the stress relief cuts prevent the stress from clamping to propagate to the optic area of the crystal.
