DX-7 Seed-Crystal Orientation Unit is the unit specially designed to make and test the seed crystals. At the right it is the quartz-ingot orientation work table, where the quartz ingot gets stuck onto the fixture and the angle gets adjusted under x-ray, and, then, you can move the quartz ingot with fixture onto the other unit to process the crystal seed; at the left work table it measures the seed-crystal end-product angle. The both work tables can be designed as the seed-crystal measurement mode to test the seed-crystal angles in different sizes.
